Incidentally, as a user it drives me up the wall when I search for something, find a promising page in g### -- and then the searched-for text is nowhere to be found, not even in the page source. Sometimes it shows up in an archived copy. But it hardly ever leads me to say "Well, as long as I'm here..."

That's because Google in it's infinite wisdom decided that you weren't really looking for one or more of the words that you typed and that the results served up had more relevance to what they think you are looking for. Then they decided to change the + option (see [webmasterworld.com...] e.g. +word that meant you REALLY did want that word in the results, now you have to put quotes around the word to achieve that instead. So now when you search and you do want ALL of the words in the results, you have to type "word1" "word2" etc.
