Using SearchArgumentFacgtory

I'm using the Search Argument factory to configure my query predicates to
the underlying ORC file. I'm receiving the predicates through another a
custom engine and not through the Hive.
Is there any way i can build the sarg object using some form of a string
expression ?

Thanks

No. Currently there is no way to create SARG directly from string. With plain strings its hard differentiate column references vs constants vs expressions. 

You should write a conversion layer that converts the predicates from your custom engine to SARG using the direct APIs.
