Subject Re: mm is not working if you have same term multiple times in query
Date Fri, 22 Sep 2017 13:39:32 GMT
We can't use shingles as user can query lock and lock ,or any other
combination although and and some other words can be passed in stop word
processing but can't rely on that completely.

It seems to me that all OOTB solution would include some query parsing on
client side.
If those are adjacent values, you could try play with shingles to get it to
Brainstorming: custom token filter that would assign token occurrence
number to each token: e.g.
“foo lock bar lock” would be indexed as foo1 lock1 bar1 lock2, but that
would mess score…

Maybe there is something specific about your usecase that could be used to
make it work.
