The other day I came across a search engine namely ErrorKey that specifically for error codes and messages. It is a search service which I think it is a trend-right and should be bookmarked in the browsers for the programmers, whether she/he is a newbie, or an advanced programmer. I find it quite useful for me as well because shamelessly to say, I won’t be able to know all the error codes, or error messages when I write a certain Web software, as all the libraries are becoming more and more complex and amazingly sophisticated nowadays.

The below is a typical example I tried to test this ErrorKey, a keyword “Python” will instantly generate a succinct list of comprehensive explanation of this keyword search. Currently, it supports the error code search for the following operating systems and languages such as Oracle, Sybase, Apple, Cisco 6400, Unix Solaris, DB2, MySQL, PostgreSQL, SAP DB, Borland C, Python, HTTP, Symbian, etc. Its business model is based on Google AdSense.
