Google is the Web Search engine that I use more often, but I would like to know if there are web apps were you can define a list of search engines or webisite you want to retrieve the data for, in a single shot.
The idea is to specify, for example, that I want retrieve the search results from:
- 10 top results from Google
- 10 from Bing
- 10 from Microsoft MSDN Forums
- 10 from Stack Overflow
Do you know something useful?
