Issue with "Create a search query based on a requisition"

Summary

How to change the standard Search Query Form

Content

Hi

A standard search page appears when I go to a requisition and then click on the icon which says - Create a search query based on a requisition file.

The queries are -
1. From where the standard search page gets created when I click on the icon – “Create search query based on this requisition”
2. How can I change it to load with my set of fields without using the customize button?
3. I want my own default search page to appear when I click on the icon of – Create Search query based on this requisition.
