Merged [5519] from adam@nostrum.com:

Two changes: (1) searches by substring rather than
\'begins with\' (to allow, e.g., searching by last name);
and (2) limits results to 10 entries (to limit server
load and limit effectiveness of email-scraping attacks)
 - Legacy-Id: 5531
Note: SVN reference [5519] has been migrated to Git commit 2e740dc
