Krugle, most famous open-source code search engine, now powers the Yahoo Developer Network search. Not a simple step for Yahoo though, because Yahoo just a few months back scrapped its Java code and developed its pages using PHP. If you ask what Java has to do with Krugle, then this is the answer.
Krugle is built on top of Apache Lucene, 100% Java based search engine API. Is Yahoo coming back to Java?
Developers talk: You can just try your hands on Lucene with just 4 or 5 lines of code. Please search for Lucene/Nutch for more details. Mind blowing.
