Re: Want to support "did you mean xxx" but is Chinese
Hi Li Li, Thanks for your detail explanation. Basically I have similar implementation like yours. I just want to know if there is a better and total solution.

Hmmm problem? Not terribly so, is it?
Certainly I'm more for a de-XMLification of configuration myself though. And
we probably should bake-in all the basic field types so they aren't explicitly
declared (but could still be overridden if desired).
> e.g. optional sub-schema files that can be turned off and on?
Hmmm... you can use XInclude stuff. Not sure that gives you the "optional"
part of things exactly, but there is also the ${sys.prop.name[:default_value]}
syntax that can be used in the configuration to pull off conditional types of
tricks in some cases.
Right, so no designed solution to the problem, I suppose. It's what it is at
this point.
I'm curious to hear more elaboration on the specifics of how this is a problem
though. Certainly there is much room for improvement in most things.

questions on query format
Hi,
I've spent quite some time reading up on the query format and can't seem to
solve this problem:
1. If send solr the following query:
q={!lucene}profile_description:*
I get what I would expect.
2. If send solr the following query:
q=*:*
I get nothing just:
Would appreciate some insight into what is going on.

Define "not working". Show what you're getting and what you expect to find. Show your data. Note that the example given boosts on quite coarse dates, it *tends* to make documents published in a particular *year* score higher.

Re: questions about autocommit & committing documents
A full commit of all pending documents is performed whenever the first trigger is reached. So, maxdocs = 1000. Max time=1 minute. Index a packet with 999 docs. Index another packet with 50 documents immediately after. One commit of 1049 documents happens Index a packet of 999 docs. Do nothing for a minute. One commit of 999 docs happens because of maxtime... But I have to ask, "why do you care"? What high level problem are you trying to handle?

You cannot update a single field in a document in Solr, you need to

Re: SOLRNET combine LocalParams with SolrMultipleCriteriaQuery?
Hmmm, this is the Java forum, you might get a faster respons on the Solr .net
users list Especially since I don't find any reference to
SolrMultipleCriteriaQuery
in the Java 3.x code

Re: inconsistent results when faceting on multivalued field
I think the key here is you are a bit confused about what the multiValued thing is all about. The fq clause says, essentially, "restrict all my search results to the documents where 1213206 occurs in sou_codeMetier. That's *all* the fq clause does. Now, by saying facet.field=sou_codeMetier you're asking Solr to count the number of documents that exist for each unique value in that field. A single document can be counted many times. Each "bucket" is a unique value in the field. On the other hand, saying facet.query=sou_codeMetier:[1213206 TO 1213206] you're asking Solr to count all the documents that make it through your query (*:* in this case) with *any* value in the indicated range. Facet queries really have nothing to do with filter queries. That is, facet queries in no way restrict the documents that are returned, they just indicate ways of counting documents into buckets Best Erick On Fri, Oct 21, 2011 at 10:01 AM, Darren Govoni wrote: > My interpretation of your results are that your FQ found 1281 documents > with 1213206 value in sou_codeMetier field.

Re: how to handle large relational data in Solr
In addition to Otis' suggestion, think about using multivalued fields with an increment gap of, say, 100 (assuming your accessories had less than 100 fields). Then you can do proximity searches with a size < 100 (e.g. "red swing"~90) would not match across your multiple entries If this is clear as mud, write back with what you've tried and maybe we can help Best Erick On Thu, Oct 20, 2011 at 7:23 PM, Jonathan Carothers wrote: > Actually, that's the root of my concern.

Re: Question about near query order
Just to chime in here... You will get different results for "A B"~2 and "B A"~2. In the simple two-term case, changing the order requires an extra move(s). There's a very good explanation of this in Lucene In Action II.

Right, but consider the general case. You could potentially return every document in your index in a single packet with this functionality.

Re: multiple document types in a core
Yes, stored fields are placed verbatim for every doc. But I wonder at the utility of trying to share stored information. The stored info is put in certain files in the index, see: http://lucene.apache.org/java/3_0_2/fileformats.html#file-names and the files that store data are pretty much irrelevant to searching, the data in them is only referenced when assembling the document for return. So by adding this complexity you'll be saving a bit on file transfers when replicating your index, but not much else. Is it worth it? If so, why?

So there would be no way to, for example, collapse just the videos or > images like they do in google. When using the group.field option values must be the same otherwise they don't get grouped together. Maybe fuzzy grouping would be nice. Grouping videos and images based on mimetype should be easy, right? Videos have a mimetype that start with video/ and images have a mimetype that start with image/. Storing the mime type's subtype and type in separate fields and group on the type field would do the job. Off course you need to know the mimetype during indexing, but solutions like Apache Tika can do that for you. -- Met vriendelijke groet, Martijn van Groningen
Re: questions about autocommit & committing documents
May someone explain me different use case when both or only one AutoCommit parameters is filled ? I really need to understand it. For example with these configurations : 1 or 1000 or 1 1000 Thanks to everyone -- View this message in context: http://lucene.472066.n3.nabble.com/questions-about-autocommit-committing-documents-tp1582487p3445607.html Sent from the Solr - User mailing list archive at Nabble.com.
Update document field with solrj
I want to edit document filed in solr,for example edit the author name,so i
use the following code in solrj:
params.set("literal.author","anaconda")
but the author multivalued="true" in schema and because of that "anaconde"
is not replace with it's previous name and add to the end of the author
name,
also if i omit the multivalued field or set it to false the bad request
exception happen in re-indexing file with new author field,how can i solve
this problem and delete or modify the previous document field in solrj? or
does it any config i miss in schema? thanks

Re: Implement Custom Soundex
Momo, if you have the conversion text to tokens then all you need to do is implement a custom analyzer, deploy it inside the solr webapp, then plug it into the schema. Is that the part that is hard? I thought the wiki was helpful there but may some other issue is holding you. One zoology of such analyzers is at: http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters If that is the issue, here's a one sentence explanation: if you have a new analyzer you want to declare a new field-type and field with that analyzer; queries should be going through it as well as indexing. Matching word A with word B will then happen if word A and B are converted by your analyzer to the same token (this is how cat and cats match when using the PorterStemmer for example). paul Le 16 oct. 2011 à 14:09, Momo..Lelo .. a écrit : > > Dear Gora, > > Thank you for the quick response. > > Actually I > need to do Soundex for Arabic language.

help needed on solr-uima integration
Hi, After google online, some parts in the "puzzle" still missing. The best is to find a simple example showing the whole process. Is there any example like apache-uima/examples/descriptors/tutorial/ex3 RoomNumber and DateTime integrated into solr? In particular, how to feed "text" into solr for indexing which has at least two fields? Thanks, Xue-Feng
