Algolia Search FAQ

  • An index is the place where the data used by a search engine is stored.

    It is the equivalent for search of what a “table” is for a database. Unlike a database table, an index is optimized for search operations.

    For example, in an ecommerce website, the index would be a complete list of all products with a custom ranking. Learn more here.

  • Of course! All the features that make Algolia great on desktop make it even better on mobile.

    • Typo-tolerance: if there’s one place where users make typos, it’s on mobile.
    • Speed: mobile network tends to be slower, making speed an even more critical feature.
    • Relevance: on a small screen, it’s even more essential to find the best results at the top of the list.

    We provide API clients for Swift and Objective-C, Android, Kotlin and C# to help you with your implementation.

    Additionally, we’ve created iOS and Objective-C and Android UI libraries to help you easily implement search interfaces on mobile.

  • We do not offer an on-premise solution. Algolia is only an SaaS offering. On-premise is a complete change of focus - to do both is unsustainable for us. Learn more here.

  • We’ve designed our infrastructure to handle dozens to thousands of indexing operations per second. The speed depends on many factors. It generally takes more time if you’re on a shared cluster than when your plan includes a dedicated one, because shared cluster also share processing threads.

    In most cases, the engine processes indexing operations in a matter of seconds, and search operations in a few milliseconds. Learn more here.

  • Search APIs are software components that allow developers to seamlessly introduce search capabilities to websites and applications. They provide backend tools for indexing documents, querying various types of data, managing cluster configurations, viewing search analytics, and more.
