  README states "Vearch is a cloud-native distributed vector database for efficient similarity search of embedding vectors" and "Vearch is licensed under the" Apache License 2.0; searched the body for enterprise, paid, license key and commercial: none.

The vearch package on PyPI is a thin client for a running cluster with negligible downloads of its own, so banding on it would measure neither the product nor its reach. That leaves GitHub stars as the adoption signal instead.

Vearch is a distributed vector search cluster with scalar filtering, replication and a split of roles across its master, router and partition servers, built over IVF and HNSW indexes. Its hybrid search is vector similarity plus scalar filtering only, with no full-text or lexical mode, which keeps it two steps below Vespa, a complete distributed retrieval system covering more retrieval modes.

• https://raw.githubusercontent.com/vearch/vearch/master/README.md recorded 2026-09-30

  README lists "Hybrid search" as vector search plus scalar filtering, and "Replication and elastic scaling out", and describes a "Router" and "PartitionServer (PS)" role split with "raft-based replication"; searched the body for full-text, BM25 and lexical: none.
