Do (setq imap-log t) and repeat the searches and post the *imap-log*
buffer contents.  Unless there is a silly bug in nnir, I'd say it is
your server that isn't returning the correct data.

This may be due to caching -- when you search with nnir the second
time, it re-uses the article numbers since the first search, and if
articles from the first search were cached, they will be displayed.
This is just a theory though.
