Act as Proxy search not working when using Custom Criteria in Person Security Profile

We are using a custom criteria in person security profile for our HRBPs.

The SQL builds the hierarchy stored in the External Data page from the manager up to the highest HRBP and determines the access from there.

This is working in Act as Proxy when searching using person number but when using name and email address, the page errors out without providing any results. How can we adjust this SQL to address the issue and speed up the processing time?
