The following search engines only search blogs for their results and do not include links from other kinds of webpages.
Unlike typical search engines, searches in answer engines will not give you links that have the content you are looking for. Instead you ask questions, and the answer engines answer the questions themselves.
Metasearch engines are different from other search engines in that while most search engines search only through the online content they have indexed, metasearch engines search through the content that multiple other normal search engines have indexed, giving them a greater number of items to search through and retrieve.
