Searching in Google is great but sometimes you have to wade through millions of results to find what you want. Enter What Do you Love? from Google. WDYL takes your search and turns it into categories. This reminds me of the Pinterest layout. And I love Pinterest!
Searching within a site
Some websites have a custom search engine you can use to search within the site. If it doesn't, you can use the "site" operator to create your own custom search. In the search bar (also called the omnibox), use the site operator in front of the URL to create the search. After the URL, put a space and then the search term. For example: site:www.pablopicasso.org paintings This will search the pablopicasso.org website with the search term "paintings."
You can see that all of these results are confined to the pablopicasso.org website.
