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?
Regards
Nada

Have you tried the built-in phrase processing with double quotes? e.g.
"this is a phrase"?
See the Term section at
http://lucene.apache.org/java/2_4_0/queryparsersyntax.html
