Lucene / Elastic regex flavor

[hartman]

Flavor Request for Lucene

Lucene is the foundation of many search engine technologies, most prominently perhaps Elasticsearch, itself used by a whole slew of search engine and dashboarding solutions. It uses quite a different form of regex. I always have trouble writing these queries, simply because they are quite a bit different from what is possible in pcre.

The documentation is here: https://lucene.apache.org/core/7_3_0/core/org/apache/lucene/util/automaton/RegExp.html https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html

Specifically:

• Limited set of operators
• no anchoring ^ (beginning of line) or $ (end of line)
• A few additional operators and flags

+1 for this! Please add flavor support for Elasticsearch/Lucene!
