Switching back to “Simple mode” again will show the details of your search criteria. You can modify the search expression by combining Boolean operators such as AND and OR.

The following rules apply when searching:

  • Entering more than one word will match any of the words.
  • Exact phrases can be entered with quotes such as "runbox rules".
  • Boolean operators such as AND, OR, and NOT can be used, along with – and + to include or exclude terms. For instance, you can enter: from:Gandalf AND (subject:sword OR subject:horse) -nazgul
