POST _search - dealing with parameters

It stated in for POST search:

All these search interactions take a series of parameters that are a series of name=value pairs encoded in the URL (or as an application/x-www-form-urlencoded (Specification ) submission for a POST )

How do we deal with conflicting parameters, provided as a part of the URL and as a form-urlencoded parameter? is there a rule stated anywhere in the spec?


treat them as duplicate search parameters, and handle them how you would otherwise handle duplicate parameters
