Thanks, that's a very nice feature. Would it also enable joining on the docId level, meaning that part of a document is kept in some index and another part of the same document is kept in another index ? In the example that was given in the articles & comments link, that could be for instance: articles index: - docId=1: "(1) this (2) paper (3) is (4) about (5) lucene". (numbers are positions in the doc). comments index: - docId=1: "(3) very (4) recommended". So that one would be able to know that the comment "very recommended" was written next to the word "paper". (Conceptually the query could be: articles.paper NEAR comments."very recommended"). Is this also part of the feature ? Thanks, Arnon.

I see a mention that there are some chances this will be released in 3.6... crossing my fingers :) Francisco A.
