Fieldssuch

Fieldssuch is a term used in information retrieval and database user interfaces to describe a feature that enables searches across multiple fields within a single data item using a unified query construct. Rather than composing separate field-specific queries, fieldssuch allows a user to specify target fields collectively and apply a shared predicate. The result is a consolidated result set that satisfies the condition in any of the specified fields.

Origin and usage of the term reflect discussions around multimodal search interfaces and multi-field data models in the 2010s and 2020s, and it has since been used by several vendors and academic projects to describe similar cross-field search capabilities. There is no universal standard for fieldssuch, and implementations vary in syntax and behavior.

Mechanism and implementation details vary, but typical fieldssuch queries comprise a set of fields and a predicate. A query might request items where a term appears in any of the listed fields, or where a joined condition across fields holds. Implementations may rely on per-field indexing with a fusion step, or on composite indexes that cover multiple fields. Support for exact matching, phrase queries, and fuzzy matching depends on the underlying engine.

Applications and impact of fieldssuch are seen in enterprise search, digital libraries, e-commerce product search, and log analytics, where users expect to locate information based on scattered textual data.

Limitations include maintaining consistent ranking across heterogeneous fields, increased index complexity, and potential performance costs for large datasets. See also cross-field search, multi-field indexing, boolean search, and natural language query.
