I don't actually want Google to index as much of the internet as it possibly can. I actually want streamlined indices that are tailored towards thoroughly searching a specific knowledge domain.
Edit: I would love, love, love a search engine specifically tailored towards programming questions. One that doesn't treat queries like "C# ?." as me looking for "C#" and getting the most generic results possible.
I just want a search engine that gives me AND, OR, and NOT qualifiers or something similar. Parens, too, if possible. Ideally, an sql interface, but that's probably pushing it :)
I had an idea for this where I was building a manually-constructed index of sites kind of like old-school Yahoo (related to typography), and then there would be a full-text search of those URLs and their close relatives (pretty much, the idea being that for a given URL, I'd index anything else in the same URL directory or subdirectories of that URL). I ended up giving up on it largely because time is finite and I have plenty of other projects competing for my time. I imagine something that built on the basic idea though could work, by omitting the Yahoo-style directory and instead working from a collection of vetted URL starting points.
