Finding sub string starting with punctuations inside string with word boundaries

Question

I have 2 strings. Need to check if the second string is present in the first string or not with word boundaries.

string 1 = PDS Flip - cover options not available

string 2 = - cover options not available

I have tried the following approach but not working

import regex


check_text = regex.escape("- cover options not available")
text = regex.escape("PDS Flip - cover options not available")
found = bool(regex.searh(fr"\b{check_text}\b", text))

print(found)

Actual result = False

expected result = True
