Just tried to search for threads about the NASA SSB receiver. Being simple minded I expect a search facility to return what I ask for (or at least for the first few returns) so entered:
and got every thread with nasa in the title and some that didn't. OK so I was not specific enough. I then entered the phrase in inverted commas and usual caps to show I only wanted those terms together:
and got exactly the same list of threads.
Effectively useless. Or have I missed something obvious?

Apparently it is set up this way as it minimises the overheads on the servers, presumably because as soon as it hits one of the words you are searching for, it can stop searching the rest of the thread.
The technical name for this is a primal-dual interior-point search algorithm (also know as a shift half interior term search, or S.H.I.T. search).

Use the advanced search facility on google. Searching for all the words and specifically searching YBW.com.
