Hi  
I need to parse a Json query to booleanquerybuilder. But I am not sure how to achieve this via Java api.  
For e.g  
{ "bool" : { "must" : { "term" : { "author": "xyz" } } ,"must" : { "has\_child" : {"type" : "person", "query" :{ "term" : { "name": "abc" } }} } ,"must" : { "has\_child" : {"type" : "county", "query" :{ "term" : { "city": "ny" } }} } } }

I need to parse the above json query to BooleanQueryBuilder. Can anyone help me how to achieve this?  
Thanks in advance.

There is no option to parse a json query into its builder representation. Why do you want to do it? If you want to hack the query a bit (maybe add a filter, or something similar), then parse the json into a "Map of Maps", add what you need, and add the query as a map (automatically converted to a json) to the search request.

Thank you Shay. Will try to Parse as MAP of MAPS.
