I cover an industry of which I track about 100 sites on the web for various news, information and analysis stories.

As part of this site I am thinking that the google search tool might be a nice add on

Can I set up a "XYZ search engine" where people can come to my site enter a search term have the mechanism search the 100 sites that I have set up to be included and provide results. - these are not sites that I own, but they are prominent sites on the web.

How much dominion and criteria would I have - can you do an advanced search, can results be organized by date, relevance and so on?    pricing would be based on the number of inquires - $100 for 20000 would be a good start.

Please let me know if I am thinking of this correctly and I would not be stepping on anyone's toes legally.   /Doug
