Response to: performance
Lucene performs extremeley well, given the correct configuration. We run a few lucene indexes, the largest of which contains well over 3 million records, and our site averages close to 2MM daily pageviews. Our average query response time (95th percentile) is ~80ms, and we serve thousands of requests per day using a RAM-based servlet configuration in Caucho Resin. The search algorithm is a standard TFIDF algorithm (with some additional gravy), which can be easily extended or replaced given that the source code is well designed. I would highly recommend this package, having used it over the past 3 years in a variety of applications.

  Hi drunk_injun,
  
  I am using lucene for text searches. Actually I am trying to make the searches faster.
  I just wanted some inputs regarding the configuration changes that you have made to lucene. What are h/w configurations you are using etc.
  I would be very glad to receive your replies at swati_virmani@yahoo.com
  
  TIA,

  Caveat to last message - the response time of 80ms includes our own modifications to lucene to enable additional sorting and filtering parameters. Raw query times generally average < 25ms.
