I have already indexed the filters in Smart Search (I have set the filters as "not searchable"). I installed JFilters successfully, and everything seems fine. However, although the system shows that the Jfilter indexing process completes, the indexing does not actually occur, and the message "Your 'Article' indexes must be re-indexed" remains active. I repeated the process, starting by clearing and re-indexing Smart Search, but with the same result.
