New Search functionality 20A and forward

Summary

Search is now based off of requisition rather than open search of candidate database, which causes a large issue for duplicate candidate records.

Content

We have quite a few duplicate candidate records, meaning they applied and worked here in the past, left and have now applied to be rehired. When our recruiters catch the duplicates they can merge before starting the eOffer process. But when they don't identify the duplicate it causes a host of downstream issues. TCC feed back to Taleo errors out because the employee id already exists, we have to track the person for 30 days until our Onboarding process completes before we can attempt to merge the records etc.
