With this URL, you are hitting the RequestHandler defined as <requestHandler name="...." default="true" /> in your core0/conf/solrconfig.xml. > However, using solritas, it finds many results: > > http://localhost:8983/solr/core0/itas?q=testabc With this one, you are hitting the one registered as <requestHandler name="/itas"> > Do you have any idea what the issue may be? Probably they have different default parameters configured. For example (e)dismax versus lucene query parser. lucene query parser searches testabc in your default field. dismax searches it in all of the fields defined in qf parameter. You can see the full parameter list by appending &echoParams=all to your search URL.
