Hi Senka
I can confirm that the hashtags only work for catalogue searches and not in searches in the Library.
Searches in the Library only seem to search by resource name and Topic and not content within the resource.
The interface in later versions of Totara show the filters available clearer

To only search through the Library you will have to define topics and add the resource to a topic rather than hashtags.
