How to optimize already fast indexing for real-time | Algolia

Fast indexing ensures that search results contain the most up-to-date information in a timely manner, with "timely" varying depending on each company's business activity. While standard indexing is usually fast enough for most use cases, optimizing it can add speed to advanced scenarios where data needs to be updated even faster than usual, sometimes in real-time. Advanced use cases include selective updating, non-delete indexing, crisis management, high-frequency changes like Black Friday, and real-time systems level programming. Businesses should also consider perceived performance through user interface/user experience best practices.
