I have trouble balancing between popularity and search relevance.
The trouble is combining boost factors and a mm(minimum match) of less than
100%.
The mm leads the search to return also less relevant items.
Two conflicting main scenarios exist:
- generic category search (say something like tft)
The boost is a way to adjust the weight of that field, just like you
adjust the weight of any other field. If the boost is dominating the
score, reduce the weight and vice versa.

No problem. Use a boost function. In a DisMaxRequestHandler spec
in solrconfig.xml, specify this:
popularity^0.5
This value will be added to the score

You will probably need to fuss with the multiplier to get the popularity
to the right proportion of the total score. I
