Currently, we distinguish between basic and grammar-based search.

It was proposed to reimplement the GUI for search as follows:

.

Keywords: search autocompletion javafx

In case the query is a valid lucence syntax, use that query. If the query is not a Lucene query, just take each keyword and do an OR search. -- Maybe indicate with a backbround color that the search syntax is not correct.

@koppor created a pr draft about the basic integration of a lucene parser in jabref (JabRef#8206).

[btut]

If the query is not a Lucene query, just take each keyword and do an OR search.

I would argue that an AND search would be more appropriate, except if one field appears twice. So:

author=koppor author=btut -> OR search
author=koppor title=JabRef -> AND search
