Hi Hoss,
Thanks for the detailed response.
My XY problem is:
1) I am trying to search for a complex query:
q={!type=edismax qf="abstract^0.02 title^0.08 categorysearch^0.05"
boost='eqsim(alltokens,"xyz")' v='+tokens5:"xyz" '}
Which answers my query needs. BUT, my boost function actually changes some
of the results to be of score 0, which I want to be excluded from the
result set.
2) This is why I used the frange query to solve the issue with the score 0:
q={!frange l=0 incl=false}query({!type=edismax qf="abstract^0.02 title^0.08
categorysearch^0.05" boost='eqsim(alltokens,"xyz")' v='+tokens5:"xyz" '})
But this time, the remaining results lost their *boosted* scores, and
therefore the sort by score got all mixed up.
3) I assume I can use filter queries, but from my understanding FQs
actually perform another query before the main one and these queries are
expensive in time and I would like to avoid it if possible.
Hope this explains a bit more.
Thanks,
Lev
