The Search by username text box (see the following figure) on the User Management page allows you to search for a user by a username or a keyword. You can type any alphabetic character, numeric value, or symbol (such as @, &, or # for example), or a combination of them in the search box. The search is not case-sensitive. By default, the search result will return all usernames that match the keyword or letter(s) entered and display them on the page.

Tip

Alternatively, you can use the multi-type search text book on the upper most part of every page that you open. By default, the search results will return all matching keywords or names entered. However, if you want to search for a particular user, you can select the type qualifier to restrict search results to usernames only.
