A new site making the rounds throughout the WordPress community called WPLookup.com makes finding information for specific WordPress functions a breeze. Simply type in the function you’re looking for into the search box which contains a huge font size for some reason and click the look it up button.
I tested the search engine using the wp_list_pages function and it took me right to the Codex page outlining all of the information I needed.
For now, this is a quick and easy way to navigate through the Codex as it relates to WordPress functions. Even if the search functionality is improved on the Codex itself, because WPLookup supports OpenSearch, you can add the search engine directly to your browser meaning I’ll probably be using WPLookup versus the Codex for some time to come.
