Visszakeresés

Visszakeresés is a Hungarian term used in information science and computing to denote the retrieval of data from stored records or the tracing of information back to its source. Etymologically, vissza means back or again, and keresés means search, so the term literally denotes a “search back” or “retrieval.” In practice, visszakeresés can describe several related activities: retrieving previously indexed results in a search system; performing a reverse lookup that maps from an identifier to a human-readable record or from an IP address to a domain; reconstructing a data path or provenance in algorithmic or data-processing contexts; and tracing references in bibliographic or archival work to locate related materials.

The concept is often distinguished from general keresés by emphasizing the reuse or re-identification of existing data rather than discovery of entirely new information. In databases and information systems, visszakeresés relies on indexing, metadata, and referential integrity to enable efficient retrieval. In library science and archival practice, it underpins cataloging and provenance tracking, allowing users to follow chains of references or locate copies across collections.
