//! Query parsing, planning, and execution.

//! The primary query type is `Retrieve` -- a typed AST representing
//! "given these constraints, rank content for me." Constructed via
//! `RetrieveBuilder` or (M3+) parsed from the query language.
//!
//! The `Search` query type combines BM25 text retrieval, ANN vector retrieval,
//! and RRF fusion with the same personalization, filtering, and diversity
//! pipeline as `Retrieve`. Constructed via `SearchBuilder`.
