Boolean Search Operators

  • The Boolean search operator AND is equal to the "&" symbol.
  • The Boolean search operator OR is equal to the "|" symbol.
  • The Boolean search operator NOT is equal to the "!" symbol.


Using AND narows a search by combining terms; it will retrieve emails that use both the search terms you specify, as in this example:

  • July & Discount

Using OR broadens a search to include results that contain either of the words you type in.

  • July | August

Using NOT will narrow a search by excluding certain search terms.

  • !July

You can always combine multiple search strategies to focus your search to ensure that you find just the emails you want. Here are some examples of more complex searches.

  • (July | August) & Discount
  • July & (!Discount)
