I am currently implementing a RESTful API for Elastic Search. Is there a way to query ES with a generic value? For example, this will allow the user to pass in any key and value and this would convert the value to whatever typeof field it is. I feel like I am complicating it. Is there a simpler way to query ES with generic values being passed to it?

Ex:

I could pass the following: POST command -

RulesGreaterThanDictionary is : 

  public Dictionary<string, Object> RulesGreaterThanDictionary { get; set; }

And the POST call is :

  {
        "RuleEquals":
        {
          "RulesEqualDictionary":
          {
            "email" : "ggg@gmail.com",
            "validUser" : true
          }
        },
          "RuleGreaterThan" : 
        {
            "RulesGreaterThanDictionary" : 
            {
              "minamount" : 10
            }
        }
    }

As this would query ES to find documents that have email equal to some email, and is a valid user as well as the minamount of the item is at least 10.

Something generic like that.

Has this already been implemented before? Thank you!

Another possibility is to write a wrapper 

public class ValueWrapper {
    ... 
    public static final String VALUE = "value";

    private T value;

    // getter & setter
}

and than map the wrapper instead of you object which can be gerneric :)
