Why the models rank Meilisearch — on best open-source search engines for product catalogs
“Superb developer experience, strong out-of-the-box relevance, typo handling, facets, filters, sorting, synonyms, and hybrid semantic search; often the fastest route from catalog data to polished search.”
Why the models rank OpenSearch — on best open-source search engines for product catalogs
“The pick when the catalog is one workload among many — proven horizontal scale to hundreds of millions of documents, mature aggregations for faceted navigation, learning-to-rank and neural/vector search plugins, and a genuinely open (Apache-2.0) governance under the Linux Foundation; the safe default for enterprises already on AWS. Near-tie with Elasticsearch (AGPL since 2024), ranked here for the cleaner open-source license story.”
