Hi, Why don't you just use two indexes? You probably do not hate to index the test set at all.
If you have two or more subsets, just use filters that only matches the subsets you are interested in. Counting documents and such that do contain a certain term in one of the subset becomes then a search over the filtered document index and counting the number of results. Filters are quite efficient.

For that I need to split the index in two. So i have a learning set and a validation set. The problem is that I don't know how to ask lucene to give me,for exemple, the number of documents IN ONLY ONE of these subsets containing a specific term. For example, I would to get number of document containing term "hello" in a subset of document. This subset is a set of the document number({5,3} and the complete index would contains document {0,1,2,3,4,5}) How can I do this in an efficient way? I tried to get all document containing the term and then verify which document belong to my subset. However, it appears that it's very slow to do this.
