We've had several reports of weird behaviour at the European mirror
site of AltaVista (http://www.altavista.telia.com/). This is not the
changing number of results syndrome, which by the way appears to be
becoming more common on both the main and mirror sites and at all
times of the day. AltaVista Telia tells you how many documents match
your terms and you start to plough through them page by page. On some
occasions, it comes up with the "No documents found ...." even though
you may only be on number 31 in a list of perhaps 274.
So far we have worked out the following:
1. It only seems to happen when you use the more advanced search
features, for example quote marks round phrases, plus signs, fielded
searches e.g. URL:
2. Rerunning the search a few minutes or hours later does not seem to
make much difference
3. It doesn't matter at what time of day you carry out the search :-(
4. It doesn't matter how you access the results pages: if you work
your way through the pages and get "No documents found" on the fourth
set of results page, going direct to the fourth page still gives you
no documents found. So it appears that for some reason AV stops
compiling the results list.
5. Even on the results pages that say "No documents.....", the number
of documents given at the top of the page clearly indicates that there
are a lot more documents.
I am waiting for a response from AltaVista, but in the meantime has
anyone else been affected by this or found out what is going on?
