spotipy: 'Search' funtion does not retrieve all playlists

Describe the bug When ‘Search’ function is used to query playlists matching certan key words, the results do not contain playlists, which are available on official web page of spotify. The search query is the same. While in results of Official Webpage of Spotify I can see playlists, created by Spotify (where owner of playlist is user with id=spotify), in results of Spotipy Library with the same search query, I sometimes get playlists created by Spotify user, sometimes I do not get any.

Your code

playlists = []
for offset in range(0, 1000, 50):
  playlists = playlists + spotify.search(q="Folk punk", limit=50, offset=offset, type='playlist').get('playlists')['items']

Expected behavior I expect to retrieve from Spotipy the same results that I can get from Spotify Web Page.

Output (https://open.spotify.com/search/Folk punk/playlists) - here is the output that I expect to see.

Environment:

• OS: Windows
• Python version 3.7.0
• spotipy version 2.19.0
• Google Colab

Additional context Additionally, I checked function from Spotipy - user_playlists. While on https://open.spotify.com/user/spotify page I can see that Spotify user has 1520 public playlists, with almost the same code:

spotify_playlists = []
for offset in range(0, 2000, 10):
  spotify_playlists = spotify_playlists + spotify.user_playlists(user = 'spotify', limit=10, offset=offset)['items']
print(len(spotify_playlists))

I am getting less number of playlists (1177) Is there something that I missed?
