Introduction
Currently no search engine covers the entire internet. Often a search across several searchengines is more successful than a single search engine search. Meta search engines usually
integrate several search engines with complementing indices. Harvester42 covers popularity based
search engines (Google), proprietary search algorithms (cuil), open source search engines (YaCY),
product search engines (Directindustry, Google products), Video search (youtube) and powerful
meta search engines (Polymeta, Allplus, Mamma).
