Hi, I am new to ES and trying to search using java apis. I am unable to figure out how I can provide filed specific boosting using the java apis. Here is the example: My index document looks like: \_source": { - "th\_id": 1, - "th\_name": "test name", - "th\_description": "test desc", - "th\_image": "test-img", - "th\_slug": "Make-Me-Smart", - "th\_show\_title": "Coast Tech Podcast", - "th\_sh\_category": "Alternative Health } When i search for keywords I want to boost the results higher if they found in the "th\_name" compared to they're found in some other fields. Currently I am using below code to do search: QueryBuilder qb1 = QueryBuilders.matchAllQuery(); FilterBuilder fb = FilterBuilders.orFilter( FilterBuilders.termFilter("th\_name", keyword), FilterBuilders.termFilter("th\_description", keyword), FilterBuilders.termFilter("th\_show\_title", keyword), FilterBuilders.termFilter("th\_sh\_category", keyword) ); ``` // WildcardQueryBuilder wqb = new WildcardQueryBuilder(name, ``` wildcard) log.info("Executing Query: " + qb1.toString()); SearchResponse response = client.prepareSearch("talk").setTypes("themes") .setSearchType(SearchType.DFS\_QUERY\_THEN\_FETCH).setQuery(qb1).setFilter(fb) .setFrom(start).setSize(maxRows) .setExplain(true).execute().actionGet(); Is there anything I can do at query time to boost the document if the keyword is found in "th\_name" field compared to found in other fields? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Filters are not used for scoring. They only said 'yes' or 'no'! If you want to use boost, use queries, not filters. Does it help? -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 13 mars 2013 à 22:40, Amit Patel [avpatel.257@gmail.com](mailto:avpatel.257@gmail.com) a écrit : Hi, I am new to ES and trying to search using java apis.

Hi, David is right, and the java api documentation shows you exactly how to do that : [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/java-api/query-dsl-queries.html) in the BoostingQuery part.

Thanks David and Olivier for your help. I've changed my query builder to : QueryBuilder qb1 = QueryBuilders.multiMatchQuery(keyword, "th\_name", "th\_description", "th\_show\_title", "th\_sh\_category"); And now its only searching through the given list of fileds. And I guess I would have to change the query builder to : QueryBuilder qb2 = QueryBuilders.boostingQuery().positive(QueryBuilders.termQuery("th\_name", keyword)) .negative(QueryBuilders.multiMatchQuery(keyword, "th\_description", "th\_show\_title", "th\_sh\_category")).negativeBoost(0.2f); to make the boosting work.
