I understand the reasoning behind disabling automatic backlog search, but I think there are circumstances when it is appropriate.
I added several shows (in need of backlog) with unrealistic quality expectations. I realized the problem when I did a manual search, and corrected my file size settings and series quality preference, but it seems no attempt was made to download backlogged episodes after the change.
If the search requirements have changed, shouldn’t there be a setting to do a trickle backlog? Or at least cache the indexer results beforehand for all qualities so quality could be changed without additional API hits? Because of the quality change, I have ~30 pages of “missing” episodes, and I feel like a controlled trickle search would be nicer to my indexers than doing a manual search page by page, (or even worse, “search all missing”) not to mention more convenient.
