: I have found a user comment at this page
: https://issues.apache.org/jira/browse/SOLR-1297 (Enable sorting by function
: query) where he has mentioned that there is a workaround "(main query)^0
: func(...)" that can be used to sort results by function without having to
: install "SOLR-1297" patch. Could anyone please explain this workaround a bit
: in more detail? Maybe someone could give me an example of using it?
what that is in refrence to is that instead of using something like...
q=some query
...you would use...
q=+(some query) _func_:"aFunction(yourPopularity)"
Alternately, you may want to use the "boost" QParser which lets you
multiply the scores from a regular query by the output of a function
(which is probably more along hte lines of what you want if your
popularity ranking produces a number in a bounded range from [0-1] ...
q={!boost b=aFunction(yourPopularity) v=$x} & x=some query
