The default the schema has all the fields as string without any tokenizers. So all the queries will have to be case sensitive.
For example, the below query would give results. http://localhost:8983/solr/core0/select?shards=localhost:8983/solr/core0,localhost:8983/solr/core1&q=iPo* Take a look at this wiki page for Analyzers and tokenizers http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters Thanks, Kalyan Manepalli -----Original Message----- From: Code Tester [mailto:codetester.codetes...@gmail.com] Sent: Friday, July 17, 2009 1:23 PM To: solr-user@lucene.apache.org Subject: Re: Solr MultiCore query Both schema.xml ( in example/multicore/core0/conf and example/multicore/core1/conf ) already have * <defaultSearchField>name</defaultSearchField>* Here are the following query responses: 1) http://localhost:8983/solr/core0/select?shards=localhost:8983/solr/core0,localhost:8983/solr/core1&q=*:* <response> <lst name="responseHeader"><int name="status">0</int><int name="QTime">254</int></lst><result name="response" numFound="3" start="0"><doc><str name="id">MA147LL/A</str><str name="name">Apple 60 GB iPod with Video Playback Black</str></doc><doc><str name="id">F8V7067-APL-KIT</str><str name="name">Belkin Mobile Power Cord for iPod w/ Dock</str></doc><doc><str name="id">IW-02</str><str name="name">iPod & iPod Mini USB 2.0 Cable</str></doc></result> </response> 2) http://localhost:8983/solr/core0/select?shards=localhost:8983/solr/core0,localhost:8983/solr/core1&q= *ipod* No result 3) http://localhost:8983/solr/core0/select?shards=localhost:8983/solr/core0,localhost:8983/solr/core1&q= *name:ipod *No result* * What may be happening?
