Take a look at http://svn.apache.org/repos/asf/lucene/dev/trunk/lucene/queries/src/java/org/apache/lucene/queries/BoostingQuery.java for some inspiration, especially this part: BooleanQuery result = new BooleanQuery() { @Override public Weight createWeight(IndexSearcher searcher) throws IOException { return new BooleanWeight(searcher, false) { @Override public float coord(int overlap, int max) { // your logic here when overlap == 1, > 1, etc -- lucidimagination.com --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
