Users can filter the task list and torrent list by name using regular expressions. Examples:

• name contains key

  key

• name contains key1 OR key2

  key1|key2

• name contains key1 AND key2

  (?=.*key1)(?=.*key2)

• name does NOT contain key

  ^(?!.*key)

• name contains NEITHER key1 NOR key2

  ^(?!.*(key1|key2))

• name does NOT contain key1, but contains key2

  ^(?!.*key1)(?=.*key2)
