How to use special characters in searches
If a search expression contains one or more special characters, a backslash (\) must precede each special character.
The following special characters are also operators in search expressions:
Ampersand (&)
Hyphen (-)
Asterisk (*)
Less than sign (<)
Backslash (\)
Number sign (#)
Close square bracket (])
Open square bracket ([)
Comma (,)
Pipe sign (|)
Equal sign (=)
Question mark (?)
Exclamation point (!)
Single quotation mark (')
Greater than sign (>)
 
For example, to search for the user name user#, you must type the following search expression:
user\#
If you type user#, the search returns user names that begin with user and end with a number, such as user1, user2, and so on.
