Although it does not solve my problem completely, this is a useful
tip. Thanks.

Yes, I still think that it should be possible to perform a search in a
topic and all its sub-topics recursively. I even think this should be
the default behaviour. If it is not, then at least the documentation
should be clarified to indicate that only immediate subtopics is
included in the search.

The function `gnus-topic-find-groups' looks promising. I did some
experimentation, but I was unable to find out how to use it. When given
a topic as argument, it seems to return unrelated topics as well.
