将管道|用作立交or操作符，例如：
import osmnx as oxox.config(use_cache=True, log_console=True)place = 'Berkeley, California, USA'cf = '["highway"~"motorway|motorway_link"]'G = ox.graph_from_place(place, network_type='drive', custom_filter=cf)print(len(G)) #36cf = '["highway"~"primary"]'G = ox.graph_from_place(place, network_type='drive', custom_filter=cf)print(len(G)) #11cf = '["highway"~"motorway|motorway_link|primary"]'G = ox.graph_from_place(place, network_type='drive', custom_filter=cf)print(len(G)) #47
