After so many years of putting it off I've finally migrated to Elasticsearch. Can't believe I waited this long, as choosing a local AWS server has seriously sped up general use of the forums and functions. However, since I did this some members are complaining about a change in the way Unread Content, and View New Posts is working. Apparently, prior, these would just show the last post in a thread, whereas since enabling Elasticsearch, Unread Content will return every single unread post in a thread. I did at the same time tweak the settings of the Search functionality so I don't know if it was my doing, or what the default values should have been. My settings: Not sure if it was my doing, or just a change in how things work once Elasticsearch is enabled. Any guidance appreciated! 🙂

Just as a note to future readers of this topic, the issue looks to be by the Elastisearch provider not allowing access to the task and update by query APIs. If you get any odd issues with multiple entries where there shouldn't be in streams, it's almost always update by query not working or being blocked by the host.
