Package org.apache.lucene.queryparser.flexible.core.parser

Necessary interfaces to implement text parsers.


The package org.apache.lucene.queryparser.flexible.parser contains interfaces that should be implemented by the parsers.

Parsers produce QueryNode Trees from a string object. These package still needs some work to add support to for multiple parsers.

Features that should be supported for the future, related with the parser:

  • QueryNode tree should be able convertible to any parser syntax.
  • The query syntax should support calling other parsers.
  • QueryNode tree created by multiple parsers.
