4//! text analysis (tokenization / normalization / stop words), expression
5//! evaluation helpers, MessagePack scan readers, and rank-fusion (RRF).

7//! This crate is consumed by `nodedb` (server), `nodedb-lite` (embedded),
8//! and `nodedb-fts` (full-text overlay). Functions are pure / `Send + Sync`
9//! and free of I/O — actual data fetch happens in the calling crate.
