Subject Re: Reason Why Query Does Not Work
Date Tue, 18 Sep 2018 18:42:54 GMT
Have a look at what debug shows in the parsed query. I think every
bracket is quite significant actually and you are generating a
different type of clause.

Also, have you thought about putting those individual clauses into
'fq' instead of jointly into 'q'? This may give you faster search too,
as Solr will not have to worry about ranking.

Regards,
   Alex.
