this isn’t a delay in indexing. it’s just caching. if you want to retrieve the latest results instead of cached results (or waiting for the cached version to expire), you can do a hard refresh of, say, the Explore page. how to achieve a hard refresh depends on your browser and OS, but it’s often going to be something like ctrl+F5.
