(fieldx:query)^bfieldx Google Example: a user search "coco" , my defaults search fields are title and description. But i would like boost title field more than description field to have results more relevant. Change in the MultiFieldQueryParser : add this method public static Query parse(String query, String[] fields, int[] flags, float [] boost, Analyzer analyzer) throws ParseException { { BooleanQuery bQuery = new BooleanQuery(); for (int i = 0; i < fields.length; i++) { Query q = parse(query, fields[i], analyzer); ==> q.setBoost(boost[i]); int flag = flags[i]; switch (flag) { case REQUIRED_FIELD: bQuery.add(q, BooleanClause.Occur.MUST); break; case PROHIBITED_FIELD: bQuery.add(q, BooleanClause.Occur.MUST_NOT); break; default: bQuery.add(q, BooleanClause.Occur.SHOULD); break; } } return bQuery; } } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
