Hi Daan, Can we have an exemple of your implementation?
Thx Ulrich VACHON -----Message d'origine----- De : Daan de Wit [mailto:[EMAIL PROTECTED] Envoyé : jeudi 6 novembre 2008 11:35 À : java-user@lucene.apache.org Objet : RE: Can Lucene tells which field matched ? Hi, I have implemented such a solution using the query explanation. IndexSearcher has an explain(Query query, int document) method that returns an Explanation object, on the Explanation object you can ask if it is a match with #isMatch(). You still need to repeat this for each found document though.
