GotApi.com for fast API search
I came across this cool website, gotAPI.com , a documentation search engine, which can be used for API searches. Try it yourself to know what is cool about it. It got text area to enter search criteria for example, Class Name, method name, with Google Suggest like feature. Each framework or language is put under various catagories like HTML/CSS, PHP,XML, Java. You can use two different pages to search documentation sites. start.gotapi.com page, contains check boxes to select multiple documentation sites and text area to perform search on selected sites. gotapi.com page , lists various documentation sites and once you select the documentation site, a tab will be opened for each documentation site you select and you can perform search only in that documentation site.

This is cool one man.
