Hi,  
Please help with the below scenario.

Scenario:  
The documents stored in ES will have keys "Key1" and "Key2". When from the application I send parameters for both Key1 and Key2 I need to do an "AND" condition and fetch the results. When only one parameter (Key1 or Key2) is supplied I need to query based on that key alone.

Question:  
Is there a way to achieve this in a ES directly in single query  
or in the rest api I need to construct the queries based on the inputs and execute accordingly.
