The request names no product or constraint, so there is no single answer to what to use. The sources show several platforms that offer search: Elastic is a search database for AI with search actions 616, Tavily is a real-time web search API for agents 919, Algolia is an AI search and retrieval platform with record browsing 1020, and Notion and Slack each provide search across their own workspaces 515111.
A question back: What do you want to search: the web, your own documents or workspace, or an application's own data (products, records, logs)?
