Searches through parsed resumes. Users have 3 options to create a search:
1. Match to a job description - a parsed job description is used to find candidates that suit it
2. Match to a resume - a parsed resume is used to find other candidates that have similar attributes
3. Search using custom criteria
Users should only populate 1 of jobDescription, resume or the custom criteria.
