C++ search engine inside SereneDB claiming to outperform Lucene and Tantivy on benchmarks.

Strengths
  • Zero-ETL search directly on Parquet and Iceberg files in S3 without ingestion.
  • Developed since 2016, suggesting deep engineering maturity beyond typical hobby projects.
  • Unifies Elasticsearch-like search with ClickHouse-like analytics in one Postgres-compatible system.
Weaknesses
  • Benchmarks are self-reported on their own website without independent third-party verification.
  • Tightly coupled with SereneDB ecosystem, harder to adopt as a standalone library.
