You'll probably want to influence your relevancy on this popularity number that is changing often. ExternalFileField looks like a possibility though I haven't used it. Another would be using an in-memory cache which stores all popularity numbers for any data that has its popularity updated since the last index update (say since the previous night). On second thought, it may need to be absolutely all of them but these are just #s so no big deal? You could then customize a "ValueSource" subclass which gets data from this fast in-memory up to date source. See FileFloatSource for an example that uses a file instead of an in-memory structure.
