boolean operators ("not", "and", "or") and filters matching thread IDs
or contained strings.
I'm still not fully happy with the command. It should be possible to
define a filter and then comfortably scroll through the matching
entries. Currently having to specify an index range of the unfiltered
entries is rather unhandy in combination with filtering.
