Well, maxqt is easy, it is just the number of terms that compose your query. MinTF is a strange parameter, rare terms have a low DF and most usually not a high TF, so i would keep it at 1. MinDF is more useful, it depends entirely on the size of your corpus. If you have a lot of user-generated input - meaning, bad spelled terms - then you have to set MinDF to a setting higher than the most frequent misspellings but low enough to find rare terms.
It depends on your index. -----Original message----- > From:Ali Nazemian <alinazem...@gmail.com> > Sent: Wednesday 4th February 2015 11:15 > To: solr-user@lucene.apache.org > Subject: More Like This similarity tuning > > Hi, > I am looking for a best practice on More Like This parameters.
