Filter in select single using SDP

Summary:

Filter in select single using SDP not working as expected.

Content (required):

We are currently using a SDP to populate data for a single select. The data source for this SDP is from a BO defined in the application.

The expectation is for the user to search and get the specific records from the list. This is working fine when we are not passing any 'q' parameter or if we do not specify any filterCriterion in the SDP while we call it.

But, we need to add some 'q' parameters and filterCriterion to restrict the user from seeing particular records. Once we add those we are able to achieve the restriction but the search filter is not working properly. The data is only getting highlighted instead of only showing that record in the list.
