Hosted search API with NeuralSearch hybrid keyword and semantic ranking
Algolia documents a hosted search and discovery platform at algolia.com/doc for site, app, and e-commerce search with typo tolerance, faceting, filtering, personalization, and Recommend APIs. NeuralSearch (algolia.com/doc/guides/ai-relevance/neuralsearch/get-started) adds vector search to keyword retrieval, merges ranked lists, and blends results via presets such as default, conservative, expanded_reach, and append_only; teams configure it in the dashboard or via the semanticSearch/settings API without reindexing for most preset changes. Algolia also documents official MCP offerings—Public MCP for application-scoped index exposure and Productivity MCP at https://mcp.algolia.com/mcp for user-scoped search, Recommend, and analytics workflows. SDKs cover JavaScript, Python, PHP, Java, Go, Ruby, and .NET with REST API access.

Frequently Asked Questions
- Is Algolia the same as Algolia MCP?
- Algolia is the search platform; MCP docs describe separate Public and Productivity MCP servers for connecting agents to indices and analytics.
- Does NeuralSearch require reindexing for every change?
- Algolia docs say most NeuralSearch preset and blend changes take effect immediately; reindexing is required when changing neuralExpression or vectorModelId.
- How does Algolia compare to Meilisearch or Typesense?
- Algolia is a fully hosted SaaS with NeuralSearch and Recommend; Meilisearch and Typesense offer open-source/self-hosted alternatives documented separately on this site.

Vespa
Vespa documents an open-source AI search platform at docs.vespa.ai and vespa.ai for large-scale applications combining big data, vector search, machine-learned ranking, and real-time inference. Vespa supports hybrid retrieval in a single query via YQL operators such as nearestNeighbor, weakAnd, wand, and rank(), with phased ranking profiles combining BM25, closeness, and tensor features per docs.vespa.ai/en/learn/tutorials/hybrid-search and docs.vespa.ai/en/querying/nearest-neighbor-search-guide. Built-in embedder functionality can generate text embeddings inside Vespa (tutorials reference models like snowflake-arctic-embed-xs). Vespa positions itself for RAG first-stage retrieval, recommendations, and intelligent search with sub-100ms latencies at billions of documents. Deploy self-hosted or via Vespa Cloud.
Tavily
Tavily is an AI search API designed for developers and AI applications, founded in 2023. Unlike consumer search tools, Tavily focuses on providing structured, relevant search results for AI agents and RAG (Retrieval Augmented Generation) systems. The API returns comprehensive answers with citations optimized for AI workflows. Tavily's semantic search understands query intent beyond keywords. Both free and paid tiers are available for developers integrating search into applications.
