If you want help with the API, you need to give us the exact query you have sent, as well as the answer you have received.

That makes sense. The query is going through Synology Video Station as a plugin and I understand it is likely attaching things to the query that I'm not seeing. The query there is simply "Kung Fu", it returns 10 items and they all have "Kung Fu" in the titles. However none of those returns is the 1972 series.

Then, you will have to contact the Synology support team.

I got this from Dev Tools:

type: "tvshow"
query: "Kung Fu"
prefer_lang: "enu"
season: null

Is that helpful?

If I remember correctly, displaying only the first 10 search results is an old Synology problem.
Probably what you are looking for is beyond the first 10 items.
See if previous cases can help you.

2022.08.07 : My issue is now resolved with Synology support.

Required resolution present in Video Station functionality, using Administrator login,
to edit metadata matching in combination with search function.

1. Login as administrator
2. Launch Video Station.
3. Chose content (e.g. a movie or tv show/series) with the issue.
4. Over on the far right-hand side of the screen, choose 'Edit video info' option.
5. A 'Edit video info' screen will be shown.
6. Select the 'Search from Video Info Plugin' option.
7. Ensure the required title, and language, to be matched are both present then chose 'Search' option.
8. From the search results shown, select the appropriate entry as a required match.
9. Choose the 'OK' option.
10. Check the outcome is as required.

*FYI: * Upon return to the 'Edit video info' screen, you will probably need to change the 'Lock status' to 'Unlock'.
The blue information symbol provides the reason why.

Some Synology NAS/DS Video users have appeared reporting problems.
There are different versions of Hardware and different versions of Software.
And the problems are not exactly the same for all these versions.
One of them said there was an update from Synology.
We don't know yet but it looks like this update came with this issue.
So I suggest getting help from Synology's website.

the user got some responses from Synology.

Travis Bell reported the ports used by the servers

Hi @USER, there's only 2 ports that can be used to communicate with TMDB's service.
These are your standard HTTP 80 and HTTPS 443 ports.

If your problem is not similar to any of the above cases, I suggest contacting Synology Support.
