I genereted a CSV file with (term, docId, distance) and I used the
method mostSimilarItems with UncenteredCosineSimilarity.
But this seems to produce wrong results, i don't understand why ?
Any idea ?

Yes, what he means is that item-item similarity is just a subset of
what a recommender does. You can use an in memory rec based on
item-item similarity and just ask it for those similarities.

Exactly, but i need to improve perf and i thought that an in-memory impl
will be a solution (as mentionned in my first post).
So Seb suggested to use recommender for that but i'm afraid he sent me on a
