Do you perhaps have another definition in your config

Try running jar -tfv your jar file to see what classes

it's not what you expect (Perhaps Eclipse did something
unexpected).
Given the anomaly above (the error reported doesn't correspond to

jars lying around that you somehow get to first.
Finally, is there any chance that your

which case Solr may be finding
org.apachepco.search.orchSynonymFilterFactory
but failing to load a dependency (that would have to be put in the lib

Re: Query regarding solr plugin.
Looking at things more carefully, it may be one of your dependent classes
that's not being found.
A couple of things to try.
1 when you do a 'jar -tfv yourjar, you should see
output like:
1183 Sun Jun 06 01:31:14 EDT 2010
org/apache/lucene/analysis/sinks/TokenTypeSinkTokenizer.class
and your filter statement may need the whole path, in this example...
filter class=org.apache.lucene.analysis.sinks.TokenTypeSink/ (note, this
is just an example of the pathing, this class has nothing to do with
your filter)...
2 But I'm guessing your path is actually OK, because I'd expect to be seeing a
class not found error. So my guess is that your class depends on
other jars that
aren't packaged up in your jar and if you find which ones they are and copy them
to your lib directory you'll be OK. Or your code is throwing an error
on load. Or
something like that...
3 to try to understand what's up, I'd back up a step. Make a really
stupid class
that doesn't do anything except derive from BaseTokenFilterFacotry and see if
you can load that. If you can, then your process is OK and you need to
find out what classes your new filter depend on. If you still can't, then we can
see what else we can come up with..

RE: term position question from analyzer stack for WordDelimiterFilterFactory
Sorry, that was supposed to be just another way to say the same thing... OK look here is my current situation. Even with preserveOriginal and concatAll set, I am still getting an even odder result. I set up sku=218078624 with title= Beanbag AppleTV Friction Dash Mount for GPS and index it in dev. The search and index analyzer stack are the same. When I do this search in the solr admin page I get zero results sku:218078624 title:AppleTV but when I do this search I get one result sku:218078624 title:appletv . This is the opposite of what was happening before I added the preserve original setting. In the analysis page I plug in that title and term, and it looks to me like it should match... which is why I started asking about term positions and such. I don't understand why I don't get a hit in both cases.

Automatic synonyms for multiple variations of a word
Hi, How do people handle cases where synonyms are used and there are multiple version of the original word that really need to point to the same set of synonyms? For example: Consider singular and plural of the word responsibility. One might have synonyms defined like this: responsibility, obligation, duty But the plural responsibilities is not in there, and thus it will not get expanded to the synonyms above! That's a problem. Sure, one could change the synonyms file to look like this: responsibility, responsibilities, obligation, duty But that means somebody needs to think of all variations of the word! Is there a something one can do to get all variations of the word to map to the same synonyms without having to explicitly specify all variations of the word?

There are a lot of really great talks and speakers from across the spectrum (check out lucenerevolution.org if you haven't already) on how people tackled and solved tough problems across the Lucene/Solr space. Now, it's time for _your_ toughest, most challenging Solr/Lucene questions. Back by popular demand at this year's Revolution conference, I'll be on the hot seat for Stump The Chump! -- where I'll spontaneously field Solr/Lucene questions I've never seen before in front of a hundreds of people. But in order to be a success, we need your questions/problems/challenges. Please email a description of your Lucene/Solr problem to i...@lucenerevolution.org (don't reply here, as I don't want to see it ahead of time) You can read more details online at http://bit.ly/stump-grant Even if you won't be able to make it to San Francisco, please send in any good questions you would be interested to see me tackle under the spotlight.

Negative OR in fq field not working as expected
I have a field 'type' that has several values. If it's type 'foo' then
it also has a field 'restriction_id'.
What I want is a filter query which says either it's not a 'foo' or if
it is then it has the restriction '1'
I expect two matches - one of type 'bar' and one of type 'foo'
Neither
fq=(-type:foo OR restriction_id:1)
fq={!dismax q.op=OR}-type:foo restriction_id:1
produce any results.
fq=restriction_id:1
gets the 'foo' typed result.
fq=type:bar
get the 'bar' typed result.
Either of these
fq=type:[* TO *] OR (type:foo AND restriction_id:1)
fq=type:(bar OR quux OR fleeg) OR restriction_id:1
do work but are very, very slow to the point of unusability (our indexes
are pretty large).
Searching round it seems like other people have experienced similar
issues and the answer has been Lucene just doesn't work like that
When dealing with Lucene people are strongly encouraged to think in
terms of MUST, MUST_NOT and SHOULD (which are represented in the query
parser as the prefixes +, - and the default) instead of in terms of
AND, OR, and NOT ... Lucene's Boolean Queries (and thus Lucene's
QueryParser) is not a strict Boolean Logic system, so it's best not to
try and think of it like one.

Re: Negative OR in fq field not working as expected
The solr 'lucene' query parser (that's being used there, in an fq)
sometimes has trouble with pure negative clauses in an OR.
Even though it can handle pure negative queries like -type:foo, it
has trouble with pure negative in an OR like you are doing. At least in
1.4.1, don't know if it's been improved in 3.1. I _think_ you may have
a case it has trouble with.
This is what I do instead, to rewrite the query to mean the same thing
but not give the lucene query parser trouble:
fq=( (*:* AND -type:foo) OR restriction_id:1)
*:* means everything, so (*:* AND -type:foo) means the same thing as
just -type:foo, but can get around the lucene query parsers troubles.
So that might work for you.
Dismax has even WORSE problems with pure negative, with no easy way to
get around em, so switching to dismax is probably not helpful there.

Re: normalizing the score
Thanks for the precision Hoss, that is helpful an explanation. I am still unsure how it is ever possible to display score-bars for which you need some normalization... but that's for another day. I feel indications of match quality is still somehow a science that has not blossomed yet. Sorting by score is, however, in very good shape. paul Le 25 avr. 2011 à 22:53, Chris Hostetter a écrit : : All I found was: http://search.lucidimagination.com/search/document/9d06882d97db5c59/a_question_about_solr_score : : where Hoss suggests to normalize depending on the maxScore. to be clear, i do not (nor have i ever) suggested that someone normalize based on maxScore. my point there was that when [people *insist* on providing osme sort of normalization, the maxScore is always available if they want to use it : I am not comfortable with that since, at least, I want that a search for : the wombats in a directory of mathematical concepts, and display that : all scores are pretty bad and not display 1.0 for matches that are only : on the word the. the crux of the problem is in deciding what you want to normalize relative to -- the ideal solution is to normalize relative the maximum *possible* score for *any* query against your corpus, but that's not something that's generally feasible to do (and based on experiments i tried once, it didn't seem like it would be very useful anyway) : It seems that the strategy would be to normalize by maxScore if the maxScore is bigger than 1.0. : Can you confirm that? : Isn't there going to be similar edge cases as above? : : I remember a time where Lucene results' score were always normalized. : That seems to be not in SOLR, or? once upon a time, lucene's most beginer freindly api did provide normalized scores, using the approach you described (divide by max score if max score greater then 1.0) and it had all of the problems you might expect -- but some people liked it because they had an irrational dislike for scores greater then 1.

Re: Negative OR in fq field not working as expected
Yeah, I do the (*:* AND -type:foo) OR something:else thing on my own pretty big index, and it's not slow at all. At least no slower than doing any other X OR Y where X and Y both include lots of results. Pre-warming the field cache for, in this case, the 'type' field may help. Same as it would if 'X' were just type:bar (not negated) where type:bar matched about the same number or documents as -type:foo does in your case. In general, there's nothing special that should make that slow, it's a pretty ordinary query, really. Just using weird syntax to get around lucene query parser issues. [Obligatory mention: This may have nothing to do with your issue, but I have found occasions where not having enough RAM allocated to Solr 1.4.1 can make things terribly slow, even though there is no OutOfMemory error or other error in the logs. Especially if you are doing facetting and/or StatsComponent. Excaserbated if you are using the default JVM GC strategies instead of picking some of the concurrent strategies.] On 4/25/2011 5:02 PM, Yonik Seeley wrote: On Mon, Apr 25, 2011 at 4:49 PM, Simon Wistowsi...@thegestalt.org wrote: On Mon, Apr 25, 2011 at 04:34:05PM -0400, Jonathan Rochkind said: This is what I do instead, to rewrite the query to mean the same thing but not give the lucene query parser trouble: fq=( (*:* AND -type:foo) OR restriction_id:1) *:* means everything, so (*:* AND -type:foo) means the same thing as just -type:foo, but can get around the lucene query parsers troubles.

Re: Reloading synonyms.txt without downtime
: Apparently, when one RELOADs a core, the synonyms file is not reloaded. Is this : : the expected behaviour? Is it the desired behaviour? this is not expected, nor is it desired (by me) nor can i reproduce the problem you are talking about. steps i attempted to reproduce: 1) started the example (on trunk) 2) loaded the analysis.jsp page, changed the field pulldown to type and entered text for the type name. entered bbbfoo in the Field value (Query) box, and hit the button. 3) verified that synonym filter produced ar as a query time synonym. 4) edited the example synony.txt file to add bbbxxx to the list of synonyms for bbbfoo 5) hit this url: http://localhost:8983/solr/admin/cores?action=RELOADcore=collection1 6) went back to the analysis.jsp page and hit the button again. 7) verified that the results changed, and now bbbxxx was produced as well. If you are seeing situations where after a core reload you do *not* see changes to the synonyms.txt file, then either there is an edge case bug, or perhaps you aren't changing what you think? providing more details about your setup and steps to reproduce would be helpful. : Issue https://issues.apache.org/jira/browse/SOLR-1307 mentions this a bit, but : doesn't go in a lot of depth. I don't understand this sentence ... that issue is a feature request for a (new) general way for plugins to re-init themselves (or some aspect of their config) with out requing an entire core reload, i don't see any comments in that issue (other then the one where you mention this thread) suggesting that a core reload doesn't currently cause synonyms to reload ... if you can be specific about what you mean that would be helpful. -Hoss
Problems with Spellchecker in 3.1

Bob Sandiford | Lead Software Engineer | SirsiDynix P: 800.288.8020 X6943 | bob.sandif...@sirsidynix.com www.sirsidynix.com -Original Message- From: Bob Sandiford Sent: Monday, April 25, 2011 5:34 PM To: solr-user@lucene.apache.org Subject: Hi, all. We're having some troubles with the Solr Spellcheck Response. We're running version 3.1. Overview: If we search for something really ugly like: kljhklsdjahfkljsdhf book rck then when we get back the response, there's a suggestions list for 'rck', but no suggestions list for the other two words. For 'book', that's fine, because it is 'spelled correctly' (i.e. we got hits on the word) and there shouldn't be any suggestions. For the ugly thing, though, there aren't any hits. The problem is that when we're handling the result, we can't tell the difference between no suggestions for a 'correctly spelled' term, and no suggestions for something that's odd like this. (Now - this is happening with searches that aren't as obviously garbage - this was just to illustrate the point). Our setup: We're running multiple shards, which may be part of the issue. For example, 'book' might be found in one of the shards, but not another. I don't *think* this has anything to do with our schema, since it's really how the Search Suggestions are being returned to us. What we'd really like to see is the response coming back with an indication that a word wasn't found / had no suggestions.

Scaling Search with Big Data/Hadoop and Solr now available at Lucene Revolution
I've worked with a lot of different Solr implementations, and one area that is emerging more and more is using Solr in combination with other big data solutions. My company, Lucid Imagination, has added a two-day course to our upcoming Lucene Revolution conference, Scaling Search with Big Data and Solr, that covers Hadoop Solr, on May 23-24 - it'll be at Lucene Revolution in San Francisco (the conference is on May 25-26 -- see lucenerevolution.org). Description: The class covers Hadoop from the ground up, including MapReduce, the Hadoop Distributed File System (HDFS), cluster management, etc., before continuing on to connect it to Solr. Students will study common use cases for generating search indexes from big data, typical patterns for the data processing workflow, and how to make it all work reliably at scale. We will explore in-depth an example of processing 1 billion records to create a faceted Solr search solution. This course will be presented on May 23 and 24 at the Lucene Revolution conference in San Francisco (the conference is on May 25-26 -- see lucenerevolution.org). Details here: http://lucenerevolution.org/training#solr-scaling I've been asked by a lot of Solr users whether Lucid offers anything like this, so I know there is a lot of interest out there. -Jay
solr sorting on multiple conditions, please help
Hi Folks,
I got a problem on solr sorting as below:
sort=query({!v=area_id: 78153}) desc, score desc
What I want to achieve is sort by if there is a match with area_id, then
sort by the actual score
problem is, area_id is a multiple value, the result I am getting does not
sort by the actual score even the results all matches area_id 78153
I am getting results like this
Area 2, score 0.21
Area 3, score 0.38
Area 4, score 0.23
but the result should be like this
Area 3, score 0.38
Area 4, score 0.23
Area 2, score 0.21
Thanks heaps in advanced.
Regards
James
Re: Good protwords.txt ?

Re: Automatic synonyms for multiple variations of a word
Hi Otis Robert, - Original Message How do people handle cases where synonyms are used and there are multiple version of the original word that really need to point to the same set of synonyms? For example: Consider singular and plural of the word responsibility. One might have synonyms defined like this: responsibility, obligation, duty But the plural responsibilities is not in there, and thus it will not get expanded to the synonyms above! That's a problem. Sure, one could change the synonyms file to look like this: responsibility, responsibilities, obligation, duty But that means somebody needs to think of all variations of the word! Yes, that seems to be the case now, as it was in 2008: http://search-lucene.com/m/gLwUCV0qU02subj=Re+Synonyms+and+stemming+revisited http://search-lucene.com/m/7lqdp1ldrqx (Hoss replied, but I think that suggestion doesn't actually work) Is there a something one can do to get all variations of the word to map to the same synonyms without having to explicitly specify all variations of the word? I think this is where Robert's 2+2lemma pointer may help because the 2+lemma list contains records where a headword is followed by a list of other variations of the word. The way I think this would help is by simply taking that list and turning it into the synonyms file format, and then merging in the actual synonyms. For example, if I have the word responsibility, then from 2+2lemma I should be able to get that responsibilities is one of the variants of responsibility. I should then be able to take those 2 words and stick them in synonyms file like this: responsibility, responsibilities And then append actual synonyms to that: responsibility, responsibilities, obligation, duty But I may then need to actually expand synonyms themselves, too (again using data from 2+2lemma): responsibility, responsibilities, obligation, obligations, duty, duties I haven't tried this yet.

Re: Automatic synonyms for multiple variations of a word
This has come up with stemming: you can stem your synonym list with the FieldAnalyzer Solr http call, then save the final chewed-up terms as a new synonym file. You then use that one in the analyzer stack below the stemmer filter.

Re: Automatic synonyms for multiple variations of a word
Right, instead of this in synonyms file: responsibility, obligation, duty I could stem each of the above words/synonyms and have something like this in synonyms file: respons, oblig, duti But somehow this feels bad (well, so does sticking word variations in what's supposed to be a synonyms file), partly because it means that the person adding new synonyms would need to know what they stem to (or always check it against Solr before editing the file).

Re: Query regarding solr plugin.
Thanks Erick. I have added my replies to the points you did mention. I am somewhere going wrong. I guess do I need to club both the jars or something ? If yes, how do i do that? I have no much idea about java and jar files. Please guide me here. A couple of things to try. 1 when you do a 'jar -tfv yourjar, you should see output like: 1183 Sun Jun 06 01:31:14 EDT 2010 org/apache/lucene/analysis/sinks/TokenTypeSinkTokenizer.class and your filter statement may need the whole path, in this example... filter class=org.apache.lucene.analysis.sinks.TokenTypeSink/ (note, this is just an example of the pathing, this class has nothing to do with your filter)... I could see this output.. 2 But I'm guessing your path is actually OK, because I'd expect to be seeing a class not found error. So my guess is that your class depends on other jars that aren't packaged up in your jar and if you find which ones they are and copy them to your lib directory you'll be OK. Or your code is throwing an error on load. Or something like that... There is jar - apache-solr-core-1.4.1.jar this has the BaseTokenFilterFacotry class and the Synonymfilterfactory class..I made the changes in second class file and created it as new. Now i created a jar of that java file and placed this in solr home/lib and also placed apache-solr-core-1.4.1.jar file in lib folder of solr home. [solr home - c:\orch\search\solr lib path - c:\orch\search\solr\lib] 3 to try to understand what's up, I'd back up a step. Make a really stupid class that doesn't do anything except derive from BaseTokenFilterFacotry and see if you can load that. If you can, then your process is OK and you need to find out what classes your new filter depend on. If you still can't, then we can see what else we can come up with.. I am perhaps doing same. In the synonymfilterfactory class, there is a function parse rules which takes delimiters as one of the input parameter. Here i changed comma ',' to '~' tilde symbol and thats it.
