A similar one is that adding more terms (i.e. AND) sometimes turns up things that didn't turn up before. I guess this 'PDP-11 parts' failure is an example of that. Yeah, it was pretty irritating - I just happened to notice it by chance, and then for a long time had to manually re-search. It seems to have gone away (at least on 'pdp-11') in the last few days, though? Oh, and the corollary (which people with brains faster than mine probably already realized :-): if you list something (epecially expensive!), wait a bit and do a search on the obvious terms that people are likely to use - if it doesn't turn up, cancel and try again (maybe with a slightly different title).
