For my project, I want to get a list of youtube videos for different topic ids. However, searching via search: list returns a measly 343 video ids for the biggest topic on youtube (lifestyle) for the year 2020.I am restricting it to relevanceLanguage = 'en', but this sample just seems too small. Is my request wrong? Or are most videos on YouTube not categorised and that's why search doesn't return it?
matches = []next_page_token = None while True: request = youtube.search().list( maxResults = 50, part = "snippet", order= "date", topicId = '/m/019_rr', publishedAfter = '2020-01-01T00:00:00Z', publishedBefore = '2021-01-01T00:00:00Z', regionCode="US", relevanceLanguage="en", type="video", pageToken = next_page_token ) response = request.execute() for item in response["items"]: matches.append(item) next_page_token = response.get('nextPageToken') if not next_page_token: break
