Summary: Regex Query with Backreferences
Key: LUCENE-7411
URL: https://issues.apache.org/jira/browse/LUCENE-7411
Project: Lucene - Core
Issue Type: New Feature
Components: core/search
Reporter: Martin Braun
Priority: Minor
Hi there,
I am currently working on a Regex Engine that supports Backreferences while not
losing determinism. It uses Memory Occurence Automata (MOAs) in the engine
which are more powerful than normal DFA/NFAs. The engine does no backtracking
and recognizes Regexes that cannot be evaluated deterministically as malformed.
It has become more and more mature in the last few weeks and I also implemented
a Lucene Query that uses these Patterns in the background. Now my question is:
Is there any interest for this work to be merged (or adapted) into Lucene core?

Usage example for the Lucene Query:

Cheers,
Martin
