I always thought off-topic groups did not show up in search results??
Is this broken now??

Nothing has changed here, no.

Silly me, I should have checked. Would it be worthwhile to post
in admin.suggestions? Apparently this came up 4 years ago and
you hinted that it might be an easy fix?

Well, back with the old, slow search engine, at the time I wrote that, it
may’ve been fairly easy. Two weeks after that, however, I wrote a brand new
search indexer and results engine which runs on the order of 100 times
faster, but which doesn’t make such filtering so easy. The old way, what it
did was found all the results first, then filtered out everything that wasn’t
in the group you were looking in -- a lot of waste. The new way, in addition
to being tight C code, uses a completely different approach for indexing:
every group, at every level of the hierarchy, has an index file of all
articles within that subtree. This intersection of this list and a given
word-hit’s list is computed and returned as search results. For the
top-level tree (e.g., the entire site encompassing all newsgroups), the index
file is essentially a list of all the articles (minus things like .test,
.statistics, etc.), and for any given article, the results engine doesn’t
know what group the article is in -- it’s just a very fast set processor.

Sounds like the solution is to remove .debate from the top level index file,
but leave it in the off-topic subtree index files. How hard could that be?

I think the issue is that then the only way to search for things in off-topic.debate would be to search there explicitly, and conversely, that no posts to off-topic.debate would *ever* show up in a regular search.
