Interesting that Lucene still holds the top position (didn't know that twitter is using it for search, amazing - so it should be able to deal with a lot of data)
Also now there they seem to be using more C++ for this kind of projects (the page says that Lucene also has a c++ port), in 2009 Java seems to have been prevalent.
