For Search, you can deploy a meta search engine or use one someone else has deployed; you still have the mainstream indexes at your disposal that way, but you tend to get less filtered results. You get the truest representation of the rest of the Net via the set up of your own index by writing and cultivating a web crawler. No, I won't suggest it's easy because it isn't. Nor will I suggest any type of paid service, because to be honest, once the rest of the world figures out you've got a successful business model around something they find inconvenient, welcome to legal troubles.

Each and every internet staple started as a bunch of folks doing a project. Keep an eye out for those, or become one of them. Do it for you. Nobody can tell you not to, or hold you to task for doing so. It's only when you start building up enough network effect driven inertia that you start to become that leverage point ripe for the co-opting.

Knowledge asymmetry is big business. The only way to keep people from pulling the wool over your eyes is to build what you need and have a good ole look yourself.

Be warned it isn't for the light of heart, hard-drive, or net link, and your results are only as good as your crawler.

There are also a lot of risks by perniciously going out and connecting with everything under the sun. I'd recommend keeping your forays constrained, or at least on a well insulated network.
