Increase the effectiveness of nopCommerce search by using Apache Lucene.NET full-text search engine. This plugin allows you override the default search and autocomplete functionality. The plugin also allows for fuzzy searches which allows users to find products they are looking for even if search terms are not spelled correctly.

Very basic, but it works, and represents a elegant and powerful search solution for NOP. However the Advanced Search features are ignored as another reviewer mentioned. How about implementing a true faceted search based on Lucene.NET.Facet ? Perhaps I can help fund the effort?
