Blossom search is a hosted (remote) search service, which indexes one or more web servers using a spider, and stores the results on it's own servers. When a user types a query, the form goes to the Blossom service, which does the matching and relevance ranking, and returns the results with links to the original pages on the original servers. It has modern search features such as stemming, spelling suggestions, match terms highlighted in context, and proximity-based relevance. It's now the featured search on the SearchTools.com home page.
