hi,thanks for looking into it.. with more looking into issue.. I made it working.. the issue was with the incompatible apache solr jar file..
but now I am facing new problem.... MyQParser is being called, but the query generated by the MyQParser is not being queired to solr.for example: if I queried "solr user" and after changing the query according to my needs it looks this "solr^3.2 user^1.0 (solr user)^5.0" but the solr is making use of modified query, instead it is using the original query "solr user"... Any ideas about this issue??
