Crate hermes_core 

Hermes - A minimal async search engine library

Inspired by tantivy/summavy, this library provides:

• Fully async IO with Directory abstraction for network/local/memory storage
• SSTable-based term dictionary with hot cache and lazy loading
• Bitpacked posting lists with block-level skip info
• Document store with Zstd compression
• Multiple segments with merge support
• Text and numeric field support
• Term, boolean, and boost queries
• BlockWAND / MaxScore query optimizations
