querrying

Querrying refers to the act or process of making inquiries to retrieve information from a data source, typically by issuing one or more queries. In modern use, the term is largely synonymous with querying, though querrying is a less common spelling variant.

Origin and spelling: The standard term is querying, derived from query. "Querry" is an archaic or alternative spelling that appears occasionally in historical texts or as a typographical variant; as a result, querrying is seldom employed in contemporary technical writing.

Contexts: In computing, querrying encompasses formulating and sending a query to a database, search engine, API, or knowledge base. In SQL, SPARQL, and other query languages, querries define select, filter, and join operations to retrieve data. In information retrieval, user interfaces may support natural-language querrying or structured query syntax.

Practice and pitfalls: Effective querrying involves clear criteria, precise syntax, and awareness of data schema. Poorly formed querries can yield incomplete results or high latency; optimization includes indexing, limiting result sets, and using appropriate operators.

History and variants: While "querrying" sometimes turns up in older documents or as a misspelling, most modern documentation uses "querying" or "queries" for the noun. Related terms include query, query language, information retrieval, and search.
