Meilisearch Alternative
Meilisearch is a great search engine, but it requires running a Rust binary and managing a persistent server. LumoSearch is a pure JavaScript engine that runs anywhere — including serverless — with BM25F for superior relevance scoring.

Meilisearch uses a custom bucket-sort ranking system with ordered rules. LumoSearch uses BM25F — the same algorithm powering Elasticsearch and academic IR research — giving you mathematically grounded relevance scoring.
Meilisearch requires compiling and running a Rust binary. LumoSearch is pure JavaScript/TypeScript — it runs on Node.js, in Lambda, in Cloudflare Workers, or anywhere JavaScript runs.
Meilisearch needs a persistent server with disk storage. LumoSearch Cloud runs on AWS Lambda with S3-backed indexes — no servers to manage, automatic scaling, pay only for what you use.
Meilisearch has ranking rules, sortable attributes, filterable attributes, and distinct attributes. LumoSearch has fields with weights. Configure weights at collection creation and you're done.
