Makes the search box on the Users screen also find people by their first name, last name or full name, not just username and email.
Snippet Library
Users snippets for WordPress
Snippets for user accounts, roles and profiles: extra profile fields, new columns in the users list, last-login tracking and tighter control of what each role can do. Handy for membership sites, client sites and teams with many authors.
bbPress: Keep Forum Posts Out of Site Search
