whydrogen — Serch Query Parser Library

Whydrogen is a slightly opinioated search query parser written in rust.

The syntax should be familiar to anyone who knows a bit about the "Advanced search" features of several popular search engines. It supports just words, "Quoted tokens", key:value pairs, !prefixed-values, -"negated" -key:"values and" -!prefixes.

Which keywords and prefixes work is fully customizable. The syntax is unicode aware.

For a detailed syntax description see the documentation in the lib.rs file.
