  assert find_search_term("This is my text and I am looking for a search term", "search") == ["search"]
  assert find_search_term("I need to search for the search term in this text", "search") == ["search", "search"]
  assert find_search_term("No match here", "search") == []
output: def find_search_term(text, term):
      import re
      pattern = re.compile(re.escape(term))
      return pattern.findall(text)
