Are you able to reindex the data from source? Typical practices around
search indexes is to treat them as secondary stores for full-text search
that mirrors a primary database or data store.

Hi,
It is possible to use SOLR which only requires schema configurations for use
(based on Lucene). You'll still need some java to look at the source code and
understand things better.
But it's potentially a Java free route to make it work for you as a search
solution.
Hope that helps,

There is indeed no search(Query) method in 3.0.
Your best bet is to compile your application against 2.9 and fix any
deprecation warnings - see the javadocs for alternatives. If it
compiles cleanly against 2.9 it should also compile against 3.0.

I guess this is the string input you use for your queries, isn't it? It's
more helpful to look at the toString() output of the parsed query to see
how Lucene interpreted your input.
