QuadSearch: The metasearch engines are web services designed to transfer the user’s queries to multiple search engines. A metasearch engine does not maintain its own index of documents. It collects and reorganizes the result lists (top-k lists), then it returns the processed data to the user.

Compared to a classic single search engine, a metasearch engine offers:

Increased web coverage
Improved retrieval effectiveness
Effortless invocation of multiple search engines QuadSearch is a brand new and constantly evolving metasearch engine.

It is hosted by the Raptor web server, which belongs to the Data Engineering Laboratory (DELAB), of Aristotle University of Thessaloniki.It has been created by Leonidas Akritidis, George Voutsakelis, Dimitrios Katsaros and Panayiotis Bozanis.

Their main purpose is to build a powerful scientific tool, that will be used by the academic community in order to retrieve useful information. Their secondary objective focuses on finding better and faster ranking algorithms.

QuadSearch’s heart is the KE Algorithm, which is the mechanism that determines the classification of the collected results. KE Algorithm was invented by the founders of this engine and has also been the basis for Search Engine Analyzer. Apart from KE Algorithm, QuadSearch is capable of using a variety of several other ranking algorithms, to classify the results.
