Parsing a Lucene/Solr query and adding more clauses
Hi Team,
I am trying to write a util which can parse a Lucene/Solr query and convert
into an object representation to add more clauses to the query.
Eg.
Input: (name:John AND name:Doe)
Output: ((firstName:John OR lastName:John) AND (firstName:John OR
lastName:John))
I tried org.apache.lucene.queryparser.classic.QueryParser to parse the query
and iterate over the terms. But this doesn't give me the boolean operators
and boosting. Tried to use
org.apache.lucene.queryparser.surround.parser.QueryParser and
org.apache.lucene.queryparser.surround.query.SrndQuery. I didn't see any API
to manipulate the query.
What would be the best way to do this?
Thanks,
Balaji

This is awesome. Thanks. I will look into the API and figure out how to
manipulate the query nodes.

The Flexible query parser is what you are looking for:
