When searching for “C++”, I get an error on this line.

needles = "C++ Developer"
regal = re.compile(r"(%s)" % "|".join(needles), re.I)
# error: multiple repeat

How to avoid the above error without manipulating the needles?

    You’re looking for re.escape() to escape all the metacharacters in your plain text.

    EDIT:

    >>> re.escape("C++ Developer")
'C\\+\\+\\ Developer'
>>> re.escape(r'\+*.][')
'\\\\\\+\\*\\.\\]\\['
