YouTube API Reflecting Wrong Content - youtube-api

Question

We are trying to pull in posts for the hashtag #smartson on YouTube using the search endpoint in the v3 data API.
However, the following two posts are not appearing in the API results:
(1) https://www.youtube.com/watch?v=F93wt8fZ-vE
(2) https://www.youtube.com/watch?v=BIWXU3IsssY
If you follow both those links and view the description section, you'll notice they both contain the hashtag #smartson as the very first word of the description. Yet they don't show up in the API results when searching that hashtag.
I can, however, retrieve those posts by looking up the channel in which they are published (using the YouTube channel endpoint). Here is the response I get back for those two posts:

In that API response, the description begins simply with the word "smartson," not the hashtag.
Any insight on why the API is not in sync with the public YouTube.com link?

Answer 1

Use the Videos.list. Tried it and it doesn't ignore the hashtag.
Tried it in the API explorer and here's what I got:
"description": " . . .Tap tap tap.\n\n######tapper\n#hashtag\n#dont ignore\n##doublehashtag",
The youtube api returned the complete description, no omissions.
