Thank you Erick.
I need first to index phrases, the built-in phrase processing (with double quotes) comes in the search step. Is there any difference between : 1) start by indexing phrases and then make a phrase search 2) index terms and then search for phrases To make things clearer: What I am doing now: - In the indexing step: I am using "IndexTermGenerator" to generate term based indexes, one index for all queries I have and another one for documents (term means single word). - In the search step : Lucene matches terms in queries index with terms in documents index. What I need to do: - Index phrases ("multi" words) in addition to terms (single words) - Search for both : phrases and terms Is there any idea on how to proceed?
