Doc2SQL

Feel the power of SQL!

Demo

Look at Javadoc documentation converted in a SQLite database

http://jwork.org/doc2sql/apidb/index.php/package-summary.html

This database holds 8,000 HTML static Javadoc files with the total size of 200MB

Also, try the search engine (top right). It can identify the main class API, if you are searching for a class (type, P1D, for example), or even searches for any word in the main body of Javadoc documents. The search feature can be customized.
