Sorting Index Results by User's Score

[Phill Tornroth <fa...@gmail.com>]

I'm puzzled on whether or not Solr is the right system for solving this
problem I've got. I'm using some Solr indexes for autocompletion, and I
have a desire to rank the results by their value to the requesting user.
Essentially, I'll tally the number of times the user has chosen particular
results, and I have a need to include that value in the process of sorting
and limiting results.

This doesn't seem like a request that would be un-typical, but I'm
wondering how Solr experts suggest it be done? It seems impractical to hold
my scores elsewhere and ask Solr for unlimited results and then do the
ordering/limiting on my side.. but I don't see an obvious way to do this
within Solr itself, though the JOIN functionality and the Function Query
stuff look like they might be a part of the right solution.

Any help would be greatly appreciated.

Thanks!

Phill

Phill,

You can find a lot of blog posts describes how to sort results by an
external field. FWIW, LucidWorks Enterprise has something like relevance
feedback framework.
