Thanks ahammad for the quick reply. As suggested, I am trying out multi core way of implementing the search. I am trying out the multicore example and getting stuck at an issue. Here is what I did and the issue I am facing
1) Downloaded 1.4 and started the multicore example using java -Dsolr.solr.home=multicore -jar start.jar 2) There were 2 files present under example/multicore/exampledocs/ , which I added to 2 cores respectively. ( Totally 3 docs are present in those 2 files and all have the word 'ipod' in it ) 3) When I query using http://localhost:8983/solr/core0/select?shards=localhost:8983/solr/core0,localhost:8983/solr/core1&q=*:*I get all the 3 results. But when I query using http://localhost:8983/solr/core0/select?shards=localhost:8983/solr/core0,localhost:8983/solr/core1&q= *ipod* , I get no results :( What could be the issue ? Thanks!
