java - Elasticsearch URI based search query without source fields -

i trying execute uri based query below. don't see effect of search parameters passing. , want disable _source=false. can me query. using java perform same using java.net packages. query return no matter search parameter pass.

uri: "http://localhost:9200/twitter/twitter/_search?updatedby=xx&node=yy"

java code:

   string charset = "utf-8";              string updatedby = "xx";             string node = "yy";      string query = string.format("updatedby:%s&nodeid:%s",             urlencoder.encode(updatedby, charset),             urlencoder.encode(nodeid, charset));     system.out.println(searchesurl + "?q=" + query);      urlconnection connection = new url(searchesurl + "?q=" + query).openconnection();     connection.setrequestproperty("accept-charset", charset); 

try instead

string query = string.format("updatedby:%s+and+nodeid:%s",         urlencoder.encode(updatedby, charset),         urlencoder.encode(nodeid, charset)); urlconnection connection = new url(searchesurl + "?_source=false&q=" + query).openconnection(); 

the issue whatever sent in q= parameter needs follow query string query syntax rules , 2 constraints anded using and operator not & this: updatedby:xx , nodeid:yy

the uri want construct thus:

"http://localhost:9200/twitter/twitter/_search?q=updatedby:xx , nodeid:yy"
