I created a OneNote Document in Teams. There's no option to search in that document. It requires to open document in OneNote online or OneNote application to be able to search.
Please Fix this issue!
Also, if you use the general Teams search bar, and get OneNote results back in the 'Files' section, it only links to the section. If it linked to the actual page, then you wouldn't have to do the search again from the OneNote section itself.

Search of OneNote is available via Delve. it would be great to have the Teams search to hook into the same APIs.
Yes, I want to create a knowledge base pointing to key conversations in channel with comments and searchable keywords, and planned to do this in the Notes feature, but then the items are not searchable. This is very poor functionality
If you press ctrl + f while on one note where you can select which page it will show you a search bar. This is broken and I hope it gets fixed soon
