>>> help(re):
"|" A|B, creates an RE that will match either A or B.
With re.search(), the pattern below matches 'cool' as well as 'foo'
>>> re.search('(foo)|cool?', 'foo bar cool foobar coolbar')
<re.Match object; span=(0, 3), match='foo'>
>>> re.search('(foo)|cool?', 'cool')
<re.Match object; span=(0, 4), match='cool'>
But, the same pattern and strings won't match 'cool' if used with re.findall()
or re.finditer() because of how they work when capture-groups are present in
the pattern.

Suggest the use of non-capturing groups in re.findall() and re.finditer() docs
