zg

zg is a small Rust library for query normalization and lightweight matching.

The 0.1.0 release is intentionally narrow: it gives the future zg / zettagrep tooling a real, publishable core instead of an empty placeholder crate.

What it does today

• trims input and folds repeated whitespace
• lowercases query text for stable matching
• splits normalized terms
• checks whether all query terms occur in a candidate string

Example

use zg::{matches_query, Query};

let query = Query::new("  Rust   Search ");
assert_eq!(query.normalized(), "rust search");
assert!(matches_query("rust search", "Rust-powered search tools"));

Scope

This crate is deliberately small in 2026. The goal is to stabilize basic query handling first, then extend the crate with richer search primitives in later releases.
