When searching the streaming collections, you may have to try different search strategies, as "Native American women" is not always used as keywords, search terms, etc in descriptions of the videos.
For example: In America Latina en Video - you can search "indigenous" and films regarding the indigenous will come up in the results list.
Another tip is to use the "Browse" or "Subject" search of the streaming video database that is being searched.
For example: In Docuseek, click on "Subject." If you scroll down the page you'll see a listing for "Indigenous Spirituality and Religion" and "Indigenous Studies."
