More notes: Lucene

Recent work on Lucene of Wikipedia

Import over 1000 recors per second - included parse time for XML on a VMWare Debian on my laptop

Complex search over the 5 million documents at 300+ queries per second. Including returning the data as Open Search (RSS) format.

More than 10 times faster than Java Lucene

Quarter the memory footprint of Java Lucene

Fully binary compatible data format with Java Lucene - so you can use all the Java tools.
