Search parameters

How do I configure the component to do this:

Admins need the ability to search for specific criteria. I want to access the form submissions from online applicants. The admin can then search the database to find the most appropriate top 10 candidates (age, sex, location, availability, experience, etc.).

I have looked through the documentation and I can't figure it out. Any help would be great.

Where would I find the code I need to alter? I would like to change the id numbers to equal a search term such as a city.

I would like the admin to be able to search for relevant terms such as city, experience, qualifications, and so on. They will need to input several search criteria at once. This would result in a data report which would show candidates from a resume database which suit the job.

This is to be used to find caregivers for people with disabilities. There may be as many as 10 search terms used at once.

They would need all relevant resumes displayed. Is this possible?

Thank you.
