More like Äpplen och Apelsiner, that is, different but similar. You Swedish guys should know. Thanks for answering, David, I appreciate the attention from a founder. I also appreciate your point that Google is updating continuously and therefore not always caught up to the current state of the web. But isn't that a problem with indexing speed, not with search speed? Their search speed is still amazing, as is Altavista, and most of the other engines. Your other point about exact vs. approximate answers is unclear, I expect that Google's answers are exact for their currently available indexes at any given time. But even if they are approximate, I'd be happy with that too. The scoring on a FULLTEXT search in Mysql is "exact" but based on a formula that is approximate anyway. I'll summarize this thread best I can. >From the math I used, we started with my estimate of 10^9, which was mistaken. The real figure was 10^6, that is, Google searches fulltext about a million times faster than Mysql. Then we used Google's 10000 machines +DRAM indexing to reduce the gap to 10^2, or 100 times faster. It turns out that 100 times is about the factor that is causing my application problems. If it just ran 100 times faster it would be about as fast as a regular indexed search, and I'd be happy. A few people suggested that Mysql shouldn't try to be faster, I (and some high-support customers like Mike Wexler) disagreed. And Alex Aulbach, bless him, actually did his homework and showed that things could be much improved with smart index techniques like inverted files. Then Sergei Golubchik wrote back to say he had taken some of the good ideas and inserted them into the TODO list, although he had higher priorities at the time. And I was satisfied for now, although my application still isn't working satisfactorily due to a really slow and CPU-hungry FULLTEXT search. I think that's our story so far.
