The upgraded search function in Runbox 6 is based on the search functionality originally developed for Runbox 7.

You will find the search area at the top of the message list when clicking Search in the Webmail menu.

Runbox 6 simple search

Simply start typing to search the messages in your account. The search function will show results as you type into the field, so there is no need to manually click on a Search button.

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".
  • Wildcard matching is supported, so entering run* would match both runruns and running.
  • 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

More information about the syntax of search expressions can be found in the documentation for the search engine Runbox uses: Xapian::QueryParser Syntax
