Hi. I like Lucene (THAT'S RIGHT!), but it doesn't offer me all features I want. That's why I decided to write another JAVA engine. If the features (see below) are interested for you, and you are a developer, that would like to help me with the new engine, PLEASE let me know (use my private mail, I DO NOT WANT TO START A FLAMEWAR HERE, LARBIN IS COOL. Howgh). Thank you.
I would like to contribute to Lucene project, but I have chosen different object model for the new engine... :-( Demo runs here: http://somis4.ais.dundee.ac.uk/sheeef/index.jsp (the machine indexes *.ac.uk right now, so the speed may be slower if you try many concurrent queries). Features: - extended Boolean model with p-metrics - index compression via Golomb, Elias-Gamma, and block coding. Better than Lucene for more than 20-50%. Each inverted list is stored in the best coding method. The method is selected by "inverted list metadata" object - it is not hard-coded. - highly configurable dynamization algorithm - it guarantees a good response time for query(), insert(), delete() operations (without degradation of index structure) - universal stemming technique for almost any language (not used in demo) - on distributed architecture, insert() would not lock the index - the engine would be able to simulate Harvest structure of Brokers - ... Speed (indexing 2000 HTML documents, without stemming) Larbin-latest: 1'17" the engine: 1'22" [RH73,IBMJDK131+JIT] Regards, Leo -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
