Describe whether the search was available
A missing search button and a completed search with no candidates are different observations. On an item’s more menu, look for Edit Subtitles and record what the screen actually offers. Also record the local user and whether a subtitle plugin has been installed and configured by the administrator.
Follow the applicable branch
Emby’s manual-download guide starts with a configured subtitle plugin. In Edit Subtitles, choose the language and applicable options, run the search, and select the download arrow for a suitable candidate. If the option to search is absent, the guide directs administrators to check the user’s permission to download subtitles. If search returns no matches, review the criteria and provider availability. For an apparently wrong title, the guide also recommends checking the item’s identification and its IMDb identifier in Metadata Manager.
Verify the item before changing shared metadata
Suppose two productions share a similar title but were released in different years. A candidate list for the wrong production cannot be repaired by repeatedly changing the desired language. Compare the media item’s identity with the production you actually hold, then make any justified metadata correction carefully because it affects the catalogue. After downloading a candidate, select it in playback and inspect timing and content on that item. Keep the missing-control case separate from the no-match case in a support report; one is about access to an operation, while the other concerns what that operation could find.
Questions, answered
Should I reinstall the subtitle plugin when only one user lacks search?
First check that user’s subtitle-download permission, as Emby’s guide specifically recommends for an absent search option.
