There is many a WordPress plugin out there that enhances WordPress search but I have yet to find a plugin that will add user search.
Search Everything used to have the functionality but was removed when WP moved to version 2.8. I suspect this was due to the way WP changed how authors were stored.
The reason why I'm after user search is because all users on the WP site are staff members with their own profile. We have an author page that lists all staff by surname that is separated by 20 members per page. If you only know the first name of a member of staff then trying to find that member is very hard. I want to extend WP search so you can simply enter a name and the corresponding member shows up.
This site is an intranet so using an external search engine is out of the question.
Just want to be clear that I'm wanting to search for users not search for posts by author.
How can I get staff member search added?
