The job search matches only against featured jobs (jobs with a
promotionValue > 0). This method doesn't return any jobs having a
promotionValue <= 0. The search results order is determined by the
promotionValue (jobs with a higher promotionValue are returned higher up
in the search results), with relevance being used as a tiebreaker.
The job search matches against all jobs, and featured jobs
(jobs with promotionValue > 0) are not specially handled.
The mode of the search method isn't specified. The default search
behavior is identical to JOB_SEARCH search behavior.
