        comparisonType : ComparisonType * 
        value : Object * 
        ?includeNulls : bool 
(* Defaults:
        let _includeNulls = defaultArg includeNulls false
*)

includeNulls (Optional): Type: SystemBoolean
Shall NULL attribute values be included in the result

Return Value

SearchArgument, which contains the filter condition

Remarks

The FilterBy method is the primary means for creating filters for the objects. This method returns search argument, which filters the object, comparing the attribute value with the specified value, using the specified comparisonType. When includeNulls == true, the results also contain the objects, where the attribute value is null.
