Re: Field Collapsing SOLR-236
Hi Rakhi, Sorry, I didn't see this email until just now. Did you get it working? If not here's some things that might help. - Download the patch first. - Check the date on which the patch was released. - Download the version of the trunk that existed at that date. - Apply the patch using the patch program in linux. There is a Windows program for patching but I can't remember right now. - After applying the patch just compile the whole thing It might be better if you used the example folder first and modify the config to work for multicore (at least that's what I did) . You can compile example by doing ant example (if I remember correctly) For config stuff refer to this link : http://wiki.apache.org/solr/FieldCollapsing HTH :) - Moazzam I'd give you the On Wed, Jun 23, 2010 at 7:23 AM, Rakhi Khatwani wrote: > Hi, > But these is almost no settings in my config > heres a snapshot of what i have in my solrconfig.xml > > > > > > multipartUploadLimitInKB="2048" /> > > > default="true" /> > > class="org.apache.solr.handler.admin.AdminHandlers" /> > > > > *:* > > > > class="org.apache.solr.handler.component.CollapseComponent" /> > > > Am i goin wrong anywhere? > Regards, > Raakhi > > On Wed, Jun 23, 2010 at 3:28 PM, Govind Kanshi wrote: > >> fieldType:analyzer without class or tokenizer & filter list seems to point >> to the config - you may want to correct. >> >> >> On Wed, Jun 23, 2010 at 3:09 PM, Rakhi Khatwani >> wrote: >> >> > Hi, >> > I checked out modules & lucene from the trunk. >> > Performed a build using the following commands >> > ant clean >> > ant compile >> > ant example >> > >> > Which compiled successfully. >> > >> > >> > I then put my existing index(using schema.xml from solr1.4.0/conf/solr/) >> in >> > the multicore folder, configured solr.xml and started the server >> > >> > When i type in http://localhost:8983/solr >> > >> > i get the following error: >> > org.apache.solr.common.SolrException: Plugin init failure for >> [schema.xml] >> > fieldType:analyzer without class or tokenizer & filter list >> > at >> > >> > >> org.apache.solr.util.plugin.AbstractPluginLoader.load(AbstractPluginLoader.java:168) >> > at org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:480) >> > at org.apache.solr.schema.IndexSchema.(IndexSchema.java:122) >> > at org.apache.solr.core.CoreContainer.create(CoreContainer.java:429) >> > at org.apache.solr.core.CoreContainer.load(CoreContainer.java:286) >> > at org.apache.solr.core.CoreContainer.load(CoreContainer.java:198) >> > at >> > >> > >> org.apache.solr.core.CoreContainer$Initializer.initialize(CoreContainer.java:123) >> > at >> > >> org.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:86) >> > at org.mortbay.jetty.servlet.FilterHolder.doStart(FilterHolder.java:97) >> > at >> org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) >> > at >> > >> > >> org.mortbay.jetty.servlet.ServletHandler.initialize(ServletHandler.java:662) >> > at org.mortbay.jetty.servlet.Context.startContext(Context.java:140) >> > at >> > >> > >> org.mortbay.jetty.webapp.WebAppContext.startContext(WebAppContext.java:1250) >> > at >> > org.mortbay.jetty.handler.ContextHandler.doStart(ContextHandler.java:517) >> > at org.mortbay.jetty.webapp.WebAppContext.doStart(WebAppContext.java:467) >> > at >> org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) >> > at >> > >> > >> org.mortbay.jetty.handler.HandlerCollection.doStart(HandlerCollection.java:152) >> > at >> > >> > >> org.mortbay.jetty.handler.ContextHandlerCollection.doStart(ContextHandlerCollection.java:156) >> > at >> org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) >> > at >> > >> > >> org.mortbay.jetty.handler.HandlerCollection.doStart(HandlerCollection.java:152) >> > at >> org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) >> > at >> > org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:130) >> > at org.mortbay.jetty.Server.doStart(Server.java:224) >> > at >> org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) >> > at org.mortbay.xml.XmlConfiguration.main(XmlConfiguration.java:985) >> > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) >> > at >> > >> > >> sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) >> > at >> > >> > >> sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) >> > at java.lang.reflect.Method.invoke(Method.java:597) >> > at org.mortbay.start.Main.invokeMain(Main.java:194) >> > at org.mortbay.start.Main.start(Main.java:534) >> > at org.mortbay.start.Main.start(Main.java:441) >> > at org.mortbay.start.Main.main(Main.java:119) >> > Caused by: org.apache.solr.common.SolrException: analyzer without class >> or >> > tokenizer & filter list >> > at org.apache.solr.schema.IndexSchema.readAnalyzer(IndexSchema.java:908) >> > at org.apache.solr.schema.IndexSchema.access
Re: Realtime + Batch indexing
It's possible to get near real-time adds and updates (every two minutes in our case) with a multi-shard setup, if you have a shard dedicated to new content and have the right combination of unique identifiers on your data. I'll respond off-list with a full description of my setup.

Problem with linux
I have problems when i execute my prog on linux having this following piece of
code.
{
Document d;
Analyzer analyzer = new PorterStemAnalyzer();
System.out.println("1");
Directory index = FSDirectory.open(new File("index1"));
System.out.println("2");
IndexWriter w = new IndexWriter(index, analyzer, true,
IndexWriter.MaxFieldLength.UNLIMITED ) ; // MY PROG HANGS UP HERE
System.out.println("3");
.

.
}
Strangely this exact prog runs well on windows. It simply hangs
up(doesnt halt) while creating the IndexWriter object in linux. The account via
which im logged in has sufficient rights for the concerned folder.

Re: PDF remote streaming extract with lots of multiValues
POSTing the individual parameters (literal.id, literal.mycategory, literal.mycategory) as name value pairs to 1.4's /update/extract does work.

Re: Delta Import by ID
I'm not certain but i think what you want is something like this...
deltaQuery="select '${dataimporter.request.do_this_id}'"
deltaImportQuery="select ... from destinations
where DestID='${dataimporter.delta.id}'
"
...and then hit the handler with a URL like..
/dataimport?config=data-config.xml&command=delta-import&do_this_id=XYZ&
Normally, the job of deltaQuery is to pick a list of IDs based on the
${dataimporter.last_index_time}, and the ndeleteImportQuery fetches all
the data for those Ids -- but in your case you don't care about the
last index time, you just want to force it to index a specific id. so you
just need to select that id as is in your request params.

Re: making rotating timestamped logs from solr output
The entire wording/phrasing of your email leads me to suspect that you are using the example jetty server provided with solr (ie: java -jar start.jar) and that you aren't clear on the distinction between the logs generated by jetty and the logs generated by solr. the simple instance of Jetty thta you get when running java -jar start.jar does request logging into the example/logs directory -- while various debug/info/warn/error messages from the java code are all configured to be logged to the console specificly because it's an example, we want you to see what types of things are logged. For a "real" installation of Solr, i would recommend you look into something line init.d or "services" in windows (i think that's what they are called) to ensure that the servlet container is started as a daemon (independent of your user session). You can then configure your serlvet container to log anyway you want it to... http://wiki.apache.org/solr/SolrLogging That said: "request" logging from your servlet container only knows about the HTTP level request/response information -- it has no way of knowing about things like number of hits. those things are logged by Solr, but there is a single log message per request that does includes this information, so you can configure LogHandlers to direct copies of these specific messages to a special file (i can't remember the pattern off the top of my head) : Hello, : : I would like to log the solr console. although solr logs requests in : timestamped format, this only logs the requests, i.e. does not log : number of hits for a given query, etc. : : is there any easy way to do this other then reverting to methods for : capturing solr output.

Re: Realtime + Batch indexing
Replication does not transfer files that already exist on the slave and have the same metadata (size, last modified, etc) as the master. As far as deleting files, it will only do so if they do not exist on the master. In most cases, the only way that it would delete and copy the entire index is if the slave index were optimized after updating, which would result in different filenames with entirely different sizes and modification times. The wiki has more detail: http://wiki.apache.org/solr/SolrReplication#How_does_it_work.3F My build scripts use DIH full-import for a reindex, DIH delta-import for adding new content, and the XML update handler for deletes. Replication is very fast after an update on the master. I've got my replication interval set to 15 seconds, and once it's triggered, it typically only takes a second or two. I optimize one of my shards every day, and when that happens, replicating that shard (12GB) does take a little while. On 7/8/2010 10:48 PM, bbarani wrote: One final question about replication.. When I initiate replication I thought SOLR would delete the existing index in slave and just transfers the master index in to Slave. If thats the case there wont be any sync up issues right?

AW: Sort by Day - Use of DateMathParser in Function Query?
Hi Chantal, why dont you just add another Field to your Index where u put the Day only, you can sort by this filed then in your queries cheers. -Ursprüngliche Nachricht- Von: Chantal Ackermann [mailto:chantal.ackerm...@btelligent.de] Gesendet: Freitag, 9. Juli 2010 11:45 An: solr-user@lucene.apache.org Betreff: Sort by Day - Use of DateMathParser in Function Query? Dear all, this is not a new problem, I just wanted to check whether with 1.4 there might have been changes that allow a different approach. In my query, I retrieve results that have a date field. I have to sort the result by day only, then by a different string field. The time of that date shall not be used for sorting. I cannot filter the results on a certain date (day).

Sort by Day - Use of DateMathParser in Function Query?
[P.S. to my first post] Further contemplating http://wiki.apache.org/solr/FunctionQuery. I am using 1.4.1, the date field is configured like this: (The schema has been created using the schema file from 1.4.0, and I haven't changed anything when upgrading to 1.4.1. TrieDate is said to be the default in 1.4, so I would expect this date field to have that type?) On the wiki page, the following example is listed: Example: ms(NOW/DAY) Could I do that same thing with my own date? ms(start_date/DAY) I tried that query: http://192.168.2.40:8080/solr/epg/select?qt=dismax&fl=start_date,title&sort=ms%28start_date/DAY%29%20asc,title%20asc (search for all *:* configured in solrconfig.xml for dismax) I get the following error message back: """ message can not sort on undefined field: ms(start_date/DAY) description The request sent by the client was syntactically incorrect (can not sort on undefined field: ms(start_date/DAY)). """ I am a complete newbie when it comes to function queries. Thanks for any suggestions!

Dear all, this is not a new problem, I just wanted to check whether with 1.4 there might have been changes that allow a different approach. In my query, I retrieve results that have a date field. I have to sort the result by day only, then by a different string field. The time of that date shall not be used for sorting. I cannot filter the results on a certain date (day). This thread confirms my first thought that I need another field in the index: http://search.lucidimagination.com/search/document/422dc30e0a222c28/sorting_dates_with_reduced_precision#46566037750d7b5 However, is it possible to use the DateMathParser somehow in the function queries? If it's not yet possible - why not: (a) is there are great risk that the performance would be bad? Or some other reason that discourages this solution.

Re: index format error because disk full
Disk full should never lead to index corruption (except for very old versions of Lucene). Lucene always writes (and closes) all files associated with the segment, then fsync's them, before writing & fsync'ing the segments_N file that refers to these files. Can you describe in more detail the events that led up to the zero-bytes del file? What OS/filesystem? Is there any external process that could have truncated the file? Or possibly filesystem corruption?

Re: Using hl.regex.pattern to print complete lines
Ah, this makes sense. I've changed my regex to "(?m)^.*$", and it works better, but I still get fragments before and after some returns.
