That's troubling. I wonder if there are any heuristics one/we can apply to work around this failure? We can't really add a zillion different words ('parts', etc) to searches in an attempt to work around this bug. I'd previously noticed that searches for 'pdp-11' turned up things with 'pdp11' in the title, so they apparently internally drop the '-'. (Google does a similar thing.) I just tried, and searching for '"pdp-11"' (i.e. exact multi-word match, which I use for '"Digital Equipment"') still turns up 'pdp11' items. Case ('PDP-11' versus 'pdp-11') doesn't seem to matter either. On a whim, I tried searching for '"pdp-11" "pdp-11"' (i.e. just repeated the keyword), and this time it _did_ turn it up! Very odd. I wonder why that made a difference? Well, I guess I'll just have to add that to my list of searches. Until the next one... Interestingly, this does blow up one theory that I had about what caused the failure. I had assumed they have lots of threaded lists, with e.g. all 'foo' items on a list from a 'foo' header, and when given a search for 'foo bar' they'd just go to the 'foo' list and run down it looking for items with 'bar'. So my theory was that there'd been an error, and the item in question never made it onto the 'pdp11' list; the 'pdp-11 parts' search found it via the 'parts' list. But I have no potential explanation at all how '"pdp-11" "pdp-11"' found it! FWIW, 'pdp11 pdp11' worked too. Bizarre. Noel
