Reuse query parser

[tobiasdiez]

Instead of parsing a search query using a custom grammar we should reuse some existing query parser. For example, Lucene's query parser with QueryParser.parse.

Triggered by #1633 (comment).

• Description of Lucene's syntax: http://www.solrtutorial.com/solr-query-syntax.html and https://lucene.apache.org/core/2_9_4/queryparsersyntax.html
• Lucene provides a few classes which let us modify the search syntax: https://lucene.apache.org/core/4_1_0/queryparser/index.html?org/apache/lucene/queryparser/flexible/core/parser/SyntaxParser.html
• Or we use the default Lucene syntax: https://lucene.apache.org/core/4_0_0/queryparser/org/apache/lucene/queryparser/classic/QueryParser.html

Be aware that a lot of groups rely on the current search query grammar, and they will break if this is changed.

So introducing the new parser would require to migrate all the old queries as well?

[tobiasdiez]

The only groups effected are the "search based groups". I doubt that many users use them (and then probably only experienced users). Thus, I would say that displaying a warning dialog of the kind "some groups need to be updated by hand to work properly" is sufficient. @JabRef/developers opinions?

Steps:

1. Dive into our powerful search syntax: https://docs.jabref.org/finding-sorting-and-cleaning-entries/search
2. Compare with lucene
3. Evaluate whether a switch is possible
4. Get rid off ANTLRv4
5. Add an ADR

@DominikVoigt implemented a lucene parsing at #6799. This could be a good basis to solve this issue.
