Hi, When sending a **has\_child** query to ES5.6.8 I get the following parsing exception _{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"no [query] registered for [has\_child]","line":4,"col":22}],"type":"parsing\_exception","reason":"no [query] registered for [has\_child]","line":4,"col":22},"status":400}_ This happens when running ES in embedded mode. It seems like only the **has\_child** and **has\_parent** queries are failing. I'm not seeing anything helpful in the log file either. ---

The best way to determine the cause of this would be to look at the actual query that provoke the error. Can you share that? ---
