Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science. An alternate name for the process, in the context of search engines designed to find web pages on the Internet, is web indexing.
Popular search engines focus on the full-text indexing of online, natural language documents.[1] Media types such as pictures, video,[2] audio,[3] and graphics[4] are also searchable.
Meta search engines reuse the indices of other services and do not store a local index whereas cache-based search engines permanently store the index along with the corpus. Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Larger services typically perform indexing at a predetermined time interval due to the required time and processing costs, while agent-based search engines index in [[Real time business intelligence|real time] Additionally, search engines may store a highly compressed cached version of a page, which allows them to quickly retrieve and display the most recent snapshot of a page's content.].
