[PolyFuzz](https://maartengr.github.io/PolyFuzz/) reports 801 GitHub stars, 72 forks, and 32 open issues, last pushed Jul 10, 2025. [cherche](https://github.com/raphaelsty/cherche) has 332 stars, 14 forks, and 4 open issues, last pushed Jun 1, 2024. Figures are from public GitHub metadata via [PolyFuzz's repository](https://github.com/MaartenGr/PolyFuzz) and [cherche's repository](https://github.com/raphaelsty/cherche). | | [PolyFuzz](/tools/maartengr-polyfuzz.md) | [cherche](/tools/raphaelsty-cherche.md) | | --- | --- | --- | | Tagline | Fuzzy string matching, grouping and evaluation | Neural Search | | Stars | 801 | 332 | | Forks | 72 | 14 | | Open issues | 32 | 4 | | Language | Python | Python | | Adopt for | PolyFuzz leverages advanced methods like BERT embeddings, edit distance, Levenshtein distance, and TF-IDF for sophisticated fuzzy string matching in Python datasets. | Cherche is a Python library for implementing neural search capabilities. | | Persona | - | - | | Runtime | - | - | | License | MIT | MIT | | Categories | Data & Retrieval, Evaluation & Observability | Data & Retrieval, Evaluation & Observability, Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.

Validate activity before betting a new project on cherche. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## Common questions ### What is the difference between PolyFuzz and cherche? PolyFuzz: Fuzzy string matching, grouping and evaluation. cherche: Neural Search. See the comparison table for live GitHub stats and shared categories. ### When should I choose PolyFuzz over cherche? Choose PolyFuzz over cherche when Tags unique to PolyFuzz: bert, edit-distance, embeddings, levenshtein-distance; Use PolyFuzz when your project requires deep semantic similarity detection with BERT embeddings alongside traditional string metrics; More GitHub stars (801 vs 332) - visibility, not fit. ### When should I choose cherche over PolyFuzz? Choose cherche over PolyFuzz when Tags unique to cherche: bm25, flashtext, information-retrieval, machine-learning; Also covers Vector Databases; Cherche is a Python library for implementing neural search capabilities. ### When should I avoid PolyFuzz? Avoid using PolyFuzz if you aim to match very short strings since Levenshtein distance and edit distance may dominate over BERT's nuances. Steer clear if runtime speed is a priority, as embedding computations can be resource-intensive compared to purely algorithmic methods. ### When should I avoid cherche? Last GitHub push was 815 days ago (dormant maintenance, Jun 1, 2024). Validate activity before betting a new project on cherche. Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ### Is PolyFuzz or cherche more popular on GitHub? PolyFuzz has more GitHub stars (801 vs 332). Stars measure visibility, not whether either tool fits your constraints. ### Are PolyFuzz and cherche open source? Yes - both are open-source projects on GitHub (PolyFuzz: MIT, cherche: MIT). ### Where can I find alternatives to PolyFuzz or cherche? GraphCanon lists graph-backed alternatives at [PolyFuzz alternatives](/tools/maartengr-polyfuzz/alternatives) and [cherche alternatives](/tools/raphaelsty-cherche/alternatives) ([PolyFuzz markdown twin](/tools/maartengr-polyfuzz/alternatives.md), [cherche markdown twin](/tools/raphaelsty-cherche/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/maartengr-polyfuzz-vs-raphaelsty-cherche.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, PolyFuzz or cherche? PolyFuzz: Dormant. cherche: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for PolyFuzz and cherche? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [PolyFuzz trust report](/tools/maartengr-polyfuzz/trust); [cherche trust report](/tools/raphaelsty-cherche/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=maartengr-polyfuzz`](/api/graphcanon/graph?tool=maartengr-polyfuzz) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
