I should note that this technique is probably not easily applicable to current Lucene scoring mechanism without additional development.

After checking the Lucene API of ParallelReader it seems that the star score could be stored in different index which shares the same identifier for the documents. Such index could be small (partitioned to many small indices?) so the updates can be fast. Is that what you meant Andrzej? ;-)
Anyway, I remember different technique which I once mentioned in Lucene mail list taking inspiration from book called Programming Collective Intelligence <http://www.oreilly.com/catalog/9780596529321/> . The idea is not to store score (may be I should call it user preference) into index but into neural net. One useful side effect is that this technique could score reasonably even document without any stars (meaning "similar" document to highly started documents could score better even if they haven't been stared by any user yet).

So staring will be accommodated only during indexing phase. Does it mean it will be pretty static value not a dynamically changing variable... correct? In other words if I add my starts to some document it won't affect the
scoring immediately but after indexing cycle. Correct?
(I'm not involved in Wikia development). There are some ways to go about it even in the pure Lucene-land, so that the updates are fast without reindexing the main content. Hint: ParallelReader.
