Query Rewriting

Canonical ID https://id.searchplex.net/query-rewriting/

Automatically transforming an input query into another query or query representation intended to improve retrieval or execution.

Scope

Depending on the system, rewriting may include spelling correction, normalization, expansion, reduction, phrase construction, structural changes, filters, or field-aware transformations. Usage is broader in some search-engine documentation than in academic IR.

Not equivalent to

  • Query Rewriting is not Query Expansion. Query expansion adds retrieval evidence; query rewriting may transform, normalize, constrain, or restructure a query in other ways.
  • Query Rewriting is not Query Understanding. Query understanding interprets the query; query rewriting changes the query or query representation.
