BeautifulSoup document has an error

Document link:https://www.crummy.com/software/BeautifulSoup/bs4/doc/#a-regular-expression

'If you pass in a regular expression object, Beautiful Soup will filter against that regular expression using its match() method.'

By tested it, BeautifulSoup use search() method rather than match() method.

And if it use match(), there is no need use '^' in the example:

import re
for tag in soup.find_all(re.compile("^b")):
    print(tag.name)
# body
# b
