I was happy to read in the 4.4.4 announcement that an indexing bug has been fixed. In the old forum me and another user were reporting issues with documents disappearing from indexes.
I immediately updated to 4.4.4 but unfortunately documents are still disappearing from my indexes.
I will keep an eye on the 4.4.4 behaviour if there is any difference. Please let me know if I can provide any logs or similar to get to the bottom of this.
