Thanks for response , [~dsmiley].
# it seems like bug in syntax parsing
# I trust users 
# they have many old queries in curly braces where they switch different parses (mostly \{!join}) arbitrarily, so defType isn't an option 
# it seems I achieved what uf does via luceneMatchVersion = 4.5 in config that's I'v got SOLR-11501 notes. So, uf doesn't bring any value to me. Or it should? 
# So everything seems working (switching \{!parser} inside of edismax query) until users add {{(}}braces{{)}}. 

So, old query doesn't work for them. It seems like a bug outside of SOLR-11501 or loosely related to it.
