What would a good search look like? This isn't the first time I've lived through a "search is broken!" era. Search has stopped working for me at least 3 times before: 1. When the primitive methods we had for searching usenet were overwhelmed by the growth of the internet. 2. When Yahoo finally had to admit that human curation was not going to be able to keep up with the growth of the web. 3. When Alta Vista just could not fit an index to the web inside of one computer, no matter how powerful. This current era we are in feels a lot like those old transitional eras did. In each case, the solution was to invent some kind of gee-whiz technology to index and search ever larger data sets. We now have the gee-whiz technology, but what's different this time is that it is being used to create yet more content, on every conceivable subject, and with every conceivable degree of connection (or disconnection) to the ground truth. Its really hard to see how the problem gets solved this time, but then again, it was hard to see how it was going to get solved all the previous times.
