Pass multiple fields for url query parameters for REST API

Content

I looking to create an advance filter, similar to the one in Classic Applications.  I want to pass multiple fields to filter the information that is returned on a page.  The page uses a REST API to populate a table.  I tried to setup multiple fields (lets call them SSN and Dept Name), but it only wants to filter on the first parameter in the query or statement.  Just seems to ignore the second variable.  Any thoughts or suggestions?  Has anyone else tried to do this?  Like I said it worked in Classic, but not in Visual Applications.
