Message:

jobs.wordpress.net: Enable searches in the admin for the job post type to also search certain custom fields.

Searches first_name, last_name, email, and company. Facilitates finding a job when contacted by a job poster who fails to specify the job they posted, or for finding other jobs posted by the same person/company.
