I solved this challenge by realizing that I need to match exactly and only the eight provided items in the text, and nothing else. Since the items have very distinct characters (including punctuation and special symbols like +, (), and -), a straightforward approach is to use literal matching. I built an alternation pattern where each branch is the exact string to be matched, with appropriate escaping for special regex characters (for example, dots, plus signs, and parentheses). This guarantees that if you search the text with the regex, only the eight target items will be matched and nothing else.
