I have another question, so I ask it in a new thread.
I had a post with some tags, and then I added another tag to the post and saved it. Then, when I searched the for this tag, it did not find that post with the new tag.
Only after rebuilding the index, that was found.
In another tag, also a rebuild of index did not help and it was not found.
Question is should the site editor really build the index every time some data in a post is being updated? If not, how often the index is being refreshed/rebuilt?
