I guess, I finally found the answer here: http://codegouge.blogspot.com/2014/01/modifying-solr-queryparser.html
" If you're doing development in Solr trunk and want to adjust the QueryParser, take a look at the JavaCC grammar file <https://javacc.java.net/doc/javaccgrm.html> at lucene/solr/core/src/java/org/apache/solr/parser/QueryParser.jj. This isn't a tutorial about JavaCC - there are plenty of those out there <http://cs.lmu.edu/%7Eray/notes/javacc/>. Once your changes are complete, you'll need to generate the underlying classes again. ant builds from lucene/ or lucene/solr/ don't accomplish this. So to do this, run 'ant javacc' from lucene/solr/core/. That's it.
