I started migrating my lucene search application from 2.9 version to 4.7.0
. Please suggest me the best way and best practices for this. There are
many files to rewrite.
Thank you,

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.

It is possible to use SOLR which only requires schema configurations for use

Hi,

information about the API change.
E.g. (in PyLucene)

index_reader= lucene.IndexReader.open(FSDir)
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.
