RankingAgorithm is a search library that uses a new scoring algorithm to rank results accurately and relevantly. RankingAlgorithm is very easy to use since it uses the Lucene index but ranks and scores on its own. It works in two modes, document mode and product mode.
In document mode, it ranks documents such as HTML, Wikipedia, Word/PDF docs relevantly while in Product mode, a term's occurrence is taken into account and scored accordingly. So titles starting with "wii console" are ranked first, and the others rank lower as the occurrence of "wii console" shifts in the title or gets reversed, see below:
* Wii Console and Wii Fit Plus with Balance Board Bundle (Nintendo Wii) * Wii Console System with Wii Sports Resort Game with TWO MotionPlus Attachments * Nintendo Wii Console w/ Bonus Wii Sports Resort Bundle, Black * Pelican Accessories Wii Console Stand - Nintendo Wii * Grafitti Skin for Nintendo Wii Console * NEW AC Adapter Cable Cord Power Supply For NINTENDO WII Gaming Console * Wii Remote Charging Console Stand * Nintendo Wii Skin - System Console Skin and two Wii Remote Skins - Blue Vortex * CET Domain 10301901 Console Stand Station for Nintendo Wii
RankingAlgorithm is very easy to use, as Lucene the very popular open source library can be used create the index. The results from Solr (again a very popular open source search platform) with RankingAlgorithm seems to be comparable to Google site search and much better than Lucene for Perl index searches, see comparison.
