I don’t have a simple answer for your stated issue, but maybe part of that is
because I’m not so sure what the exact problem/goal is. I mean, what’s so
special about phrase queries for your app than they need distinct processing
from individual terms?
And, ultimately, what goal are you trying to achieve? Such as, how will the
outcome of the query affect what users see and do.

Subject: Edismax query parser and phrase queries
Hi,
we are using the edismax query parser and execute queries on specific fields by
using the qf option. Like others, we are facing the problem we do not want
explicit phrase queries to be performed on some of the qf fields and also
require additional search fields for those kind of queries.
We tried to expand explicit phrases in a query by implementing some
pre-processing logic, which did not seemed to be quite convenient.
So for example (lets assume qf="title text", we want phrase queries to be
performed on the additional fields "titleAlt textAlt" ): q="ran away from home"
Cat Dog -transformTo-> q=( titleAlt:"ran away from home" OR textAlt:"ran away
from home" ) Cat Dog. Unfortunately this gets rather complicated if logic
operators are involved within the query. Is there some kind of best practice,
should we for example extend the query parser, or stick to our pre-processing
approach?
Regards,
Richard.
