Advanced Search Tips - Users

Punctuation is treated as white space in search strings with the following exceptions:

• Email addresses and Internet hostnames – Treated as single searchable tokens. 
  Example: user1@mycompany.com is treated as a single searchable token.

• Period (.) – When not followed by whitespace, a period is treated as part of a word.
  Example: 1.2 is treated as a single searchable token.

• Hyphen (-) – When a token containing a hyphen also contains a number, the complete item is treated as a part of the number. 
  Examples:
  MD-1800 is considered a searchable word, including the hyphen.
  hyphen-madness is treated as two words ("hyphen" "madness") with the hyphen treated as whitespace.
