Hi all, I'm using ElasticSearch as a search service in Spring Web project. Now I'm using Transport Client to communicate with ES. I'm wondering if there exists a method which can construct a QueryBuilder from a JSON DSL. for example, convert this bool query DSL JSON { "query" : { "bool" : { "must" : { "match" : {"content" : "quick"}, "should": { "match": {"content" : "lazy"} } } } ``` to a QueryBuilder. I need this function because I have to receive ``` user's bool string input from web front-side, and parse this bool string to a QueryBuilder. However it not suit to use QueryBuilders.boolQuery().must(matchQB).should(shouldQB).must\_not(mustNotQB). Because we may need several must or non must keywords. Thanks for your time! I'm really need some help. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, there are QueryBuilder that can parse JSON, e.g. WrapperQueryBuilder [http://javadoc.kyubu.de/elasticsearch/HEAD/org/elasticsearch/index/query/WrapperQueryBuilder.html](http://javadoc.kyubu.de/elasticsearch/HEAD/org/elasticsearch/index/query/WrapperQueryBuilder.html) wrapperQuery(java.lang.String source). This should do the job. Greets, Andrej PS: Still wondering why javadocs disappeared a while ago. This would be a great help if javadocs would be available for each version for download.

Hi Andrej, Thanks a lot for your kindly help. It's really give me a big progress. PS: I also found that QueryBuilders.wrapperQuery(String DSL) can do the same work.
