search attributes functionality is unclear

In the persistence workflow, what i'm seeing is search attribute set and get operation has the same purpose as GetDataObject.
What capability does this search attribute has other than storing some data and getting some data across workflow state?

It allows you to search -- finding the workflow by a SQL like query.

E.g. you have SA FirstName. And there are millions of worklfow executions. You want to find a workflow execution that has FirstName="John" you can find it using the query.

https://github.com/indeedeng/iwf/wiki/Persistence I have very little doc here. Sorry haven't got enough time to document all the behavior. I will start working on the documentation soon in the new year! @dennissetiawan
