Subject Using MM efficiently to get right number of results
Date Mon, 10 Feb 2020 09:23:10 GMT
I am looking for an efficient way for setting the MM(minimum should match)
parameter for my solr search queries. As we go from MM=100% to MM=0%, we
move from lots of zero result queries on one hand to too many irrelevant
results (which may then get boosted by other factors) on the other. I can
think of multiple ways to approach this:
1) Try decreasing mm from 100% to 90% to 80% in a staggered manner till you
have just the right number of results. Does not sound very efficient though.
2) Use a low value of MM, say 0%, and then pick only the top 200 results to
apply other boost factors to. Would not allow to use bf, bq, boost within

My question is, What is the standard industry practice in this matter. How
do you go about ensuring that your search returns *just the right* number
of results so that you can use other boost functions on the relevant set of

Thanks in advance
