Rust Library
Summary
Frankensearch is a two-tier hybrid search library for Rust that combines lexical and semantic search techniques. It utilizes a fast first-pass mechanism for sub-millisecond results followed by a quality-refinement stage to ensure high-accuracy rankings.
Highlights
- Two-tier hybrid architecture combining lexical (Tantivy BM25) and semantic (vector cosine) search
- High-performance execution providing sub-millisecond initial results and 150ms quality refinement
- Uses Reciprocal Rank Fusion to merge different search methodologies
- Includes a standalone CLI (fsfs) for easy installation, model management, and system diagnostics
- Supports advanced features like f16 SIMD vector indexing and feature-gated compilation
