For instance, if you're looking for pictures of Angelina Jolie, then by all means, use Google. If rather you're searching for something related to a health condition, chances are you're going to want to use a health search engine. Or if you're searching for something local, you might want to use a local search engine. Of if you're searching for a business profile, you're going to want to use a business search engine. etc. etc. etc.
Vertical niche search engines, IMO, are the only viable threat to Google's kingdom, and a great area for programmers and webmasters to develop in.

or maybe personal spiders. " if you're looking for pictures of Angelina Jolie" then you have a spider dedicated to the task. The down side, if everybody has them then all of our precious bandwidth will disappear.
Right now, they're pretty much only being used by the developers who write them, their employers, and their friends.
The most trivial while useful ones, IMHO, are simple crawlers that feed an index with a Bayesian filter. The filter gets trained with a few research papers on the chosen topic. Anything that passes the set probability, gets added to the local index. |
