SolrCloud and Optimize
Hi, I am using a recent nightly of Solr 4 and have setup a simple SolrCloud cluster of 2 shards without any replicas. If I send the 'optimize' command, then it is executed on the shards one-by-one instead of in parallel. Is this by design?How can I run optimize in parallel on all the shards? Thanks, Nikhil

Re: Semantic document format... standards?
Otis, If you are doing Named Entity Recognition, you may want to look at the research area concerned with Named Entity Recognition. :-) In general, there is inline markup and standoff markup. You seem to be going for standoff/stand-alone markup. I am not clear though whether it is just 'discovery' format or actual annotation format (with reference to where in the sentence it is with offsets or token ids). UIMA (which Solr integrate with already, right?), does NER so it must be using some sort of format. Also, TREC is one of the competitions and they provide marked-up datasets you might be able to learn something from: http://ilps.science.uva.nl/trec-entity/ If you are not sure where to start with NER, you can look at my collection of papers, though most of them are probably too specific: http://www.citeulike.org/user/arafalov Finally, if you have to deal with overlapping entities, there was an article about a month about some sort of general format.

Re: Partial search
Add debugQuery=true to your query request and look at the explain section. The scores will indicate why a document ranks as it does. When you say that your query was Energy Field, was that a quoted phrase or just two keywords? I assume the latter. I also assume that you were using the OR operator as default (not AND). Is that the case? Are you filtering out stop words at index time? I tried your three test docs on the Solr 4.0-BETA example schema (putting the doc text in the features_en dynamic field) and your query actually reorders the three docs as expected, doc3, doc2, doc1. What release of Solr are you using? There is probably additional info you are not telling us. See if you can reproduce the scenario using only the stock Solr example schema. And if you have to make changes, tell us what they are. -- Jack Krupansky -Original Message- From: Mani Sent: Tuesday, September 11, 2012 8:29 PM To: solr-user@lucene.apache.org Subject: Partial search I have three documents with the following search field (text_en type) values.

Doubts in PathHierarchyTokenizer

Retrieval of large number of documents
Hi all, I have a solr index with 5,000,000 documents and my index size is 38GB. But when I query for about 400,000 documents based on certain criteria, solr searches it really quickly but does not return data for close to 2 minutes. The unique key field is the only field i am requesting for. Also, I apply an xslt transformation to the response to get a comma separated list of unique keys. Is there a way to improve this speed?? Would sharding help in this case? I am currently using solr 4.0 beta in my application. Thanks, Rohit

Beginner questions
Hi Folks, I'm going to setup a SOLR search server for the first time. Hope you don't mind a few beginner questions. Perhaps a quick summary of how I intend to use it will help. The SOLR server will be installed on a single VPS host and bound to a internal IP (192.168.?.?). Search parameters will be received by a mod_perl script which will handle input validation, SOLR query language generation, submition to SOLR, SOLR response parsing and search request response.

In order for Solr to use this parser,
you'll need to wrap it with a QParser and QParserPlugin
implementations, then wire your implementation into
solrconfig.xml.
SurroundQParserPlugin.java (api-4_0_0-BETA) can be an example of such
implementation.

Aw: Re: Cannot parse :, using HTTP-URL as id
term query parser is your friend in this case. With this you don't need to

SolrQuery query = new SolrQuery();

Hi,
I defined a field id in my schema.xml and use it as an

I want to store URLs with a prefix in this field to be sure

foo_http://foo.com
bar_http://bar.com/?doc=452
I wrote a Java app, which uses Solrj to communicate with a

To test this, issue a java -version command from your shell (command prompt) and verify that the Java version is 1.6 or later.

How does Solr handle overloads so well?
Hi, I have been studying how server software responds to requests that cause CPU overloads (such as infinite loops). In my experiments I have observed that Solr performs unusually well when subjected to such loads. Every other piece of web software I've experimented with drops to zero service under such loads. Do you know how Solr achieves such good performance? I am guessing that when Solr is overload sheds load to make room for incoming requests, but I could not find any documentation that describes Solr's overload strategy. Experimental setup: I ran Solr 3.1 on a 12-core machine with 12 GB ram, using it index and search about 10,000 pages on MediaWiki. I test both Solr+Jetty and Solr+Tomcat. I submitted a variety of Solr queries at a rate of 300 requests per second. At the same time, I submitted overload requests at a rate of 60 requests per second. Each overload request caused an infinite loop in Solr via https://issues.apache.org/jira/browse/SOLR-2631. With Jetty about 70% of non-overload requests completed --- 95% of requests completing within 0.6 seconds. With Tomcat about 34% of non-overload requests completed --- 95% of requests completing within 0.6 seconds. I also ran Solr+Jetty with non-overload requests coming in 65 requests per second (overload requests remain at 60 requests per second). In this workload, the completion rate drops to 15% and the 95th percentile latency increases to 25. Cheers, Mike Gagnon
Re: How does Solr handle overloads so well?
Hm, I'm not sure how to approach this. Solr is not alone here - there's container like jetty, solr inside it and lucene inside solr. Next, that index is rally small, so there is no disk IO. The request rate is also not super high and if you did this over a fast connection then there are also no issues with slow response writing or with having lots of concurrent connections or running out of threads ... ...so it's not really that surprising solr keeps working :) But...tell us more.

Re: Is it possible to do an if statement in a Solr query?
If the fact that it's original vs generic is a field is_original 0/1 can you sort by is_original? Similarly, could you put a huge boost on is_original in the dismax so that document matches on is_original score higher than those that aren't original? Or is your goal to not show generics *at all*?
