Presumably there's a technical challenge with offering to match exact strings at this scale?
After all, the ability to do it was Google's main improvement over AltaVista at the time.
I'd love for someone in-the-know to share some of the technical details. Because I could bet that the sloppyness with quoted strings could be about dumbing down, but could equally be a consequence of some implementation choice at this scale and the way the data is indexed.
- marto1 5y agoMy humble guess is you'll never get these sorts of technical details from an internal so don't get your hopes up :-)
- zbuf 5y agoIf you don't ask :) I've never worked on a large-scale text indexing so it doesn't have to be a particularly sophisticated insight. I'm speculating that the majority of uses cases need some kind of work equivalency, so the major index is built that way. Whether that's just for the search terms of the average user, or ranking/clustering used to derive which pages are important. Then any additional indexes is a trade off with the magnitude of resources it would consume.
