Very strange AltaVista result

[Even Flood]

Folks!

I have just been giving a seminar on Internett searching
to several Norwegian librarians, and during that, I got some of
the strangest search results yet while trying out AltaVista.

1) I search for +diabetes. Result: 1,044,090 pages found.
2) I search for +diabetes +domain:no to get results
from Norwegian servers. Result:95 pages found.  Not much, but some.
3) Then I limit further by keeping the search string, but limiting the
language to Norwegian. Result:  1498 pages found. 
??????
4) Finally, I drop the +domain:no and limit only to +diabetes in 
Norwegian language. Result: 92 pages found. 
???????

Can anyone explain what is going on? I looked at the results under
3) and they all looked OK - in Norwegian and in domain:no. It seems
2) and 4) are badly reduced.
