Is it possible to add a boost to a has\_child query? I notice that the documentation states that a constant\_score is automatically wrapped around has\_child query, the constant\_score includes a boost field but does not seem to inherit from the has\_child query. What would be the best way to add a boost to the has\_child query? ---

You can't set it now, but I added this option: [Query DSL: Allow to set boost on has\_child query · Issue #884 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/884) (simply place boost at the query). Another option is to wrap yourself an has\_child filter with a constant\_score query, and set the boost on the constant\_score query.

Thanks Shay, wrapping the constant\_score around the has\_child worked a treat. Originally i tried building from source to apply fix you added, however i kept getting a unresolved dependencies for org.jboss.netty#netty;3.2.4.Final: when running ./gradlew command. Thanks again!

Great. Strange regarding netty, just cleared it from my local caches and it downloads fine.
