Mailing List Archive: Powered by Lucene site

Hello Lucene developers!

I want to share my happiness about such a great product Lucene is!

I've implemented website search component based on Lucene engine at
http://www.planta.de under search link.

I put here some technical details which may be will be interested for
someone.

There are 2 main part of this component which is IndexManager and
SearchWriter.

First one is used for managing website indexes (create new one,
delete, update, rebuild, set autoupdating, e.t.c) while second one
performs search over indexes and present results to end user.

I've used XSL transformation to render result pages, so page
presentation could be easily customized without touching code by
changing XSL template even in online mode.

Some attention also paid to support multi linguality (browser language
detect) in results presentation.

Please add this site to Powered by Lucene list.

Hi everybody,
we are pleased to announce that our price comparison service in germany uses
Lucene for some months now to present our visitors a very fast and very good
:-) search.

The search is implemented in four steps:
1. The product database is searched for the exact match or a phrasematch
2. if there is no match, an AND search is performed
3. if there is no match, an OR search is performed
4. if there is no match, an OR FUZZY search is performed
5. if there is no match, we give up and send everybody to eBay :-)

We also changed the StandardTokenizer, so that phrase like "Geforce4 MX440"
are tokenized to "Geforce" "4" "MX" "440", which gives better results on a
product database.
By the way we are very much looking forward to the feature of giving
Documents an additional weight. We would like to integrate our Product Rank,
that depends on the amount of views a product gets in a certain time, with
the search/index. Then a search for "geforce 4" could be additionally ranked
by our internal Product Rank and would present the graphics cards first,
that most visitors found interesting, kind of like googles PR.

Anyways, thanks a lot for the good work!

If you could add our site www.eVendi.de to the powered by page, we would be
very happy.
In case you are looking for a good link name, use "eVendi Preisvergleich".

Thanks, Christian
