No problem. Use a boost function. In a DisMaxRequestHandler spec
in solrconfig.xml, specify this:
<str name="bf">
popularity^0.5
</str>
This value will be added to the score before ranking.
You will probably need to fuss with the multiplier to get the popularity
to the right proportion of the total score. I find it handy to return the
score and the popularity value and look over a few test queries to adjust
that.
