The most efficient approach for this challenge is to use the alternation operator (|) to match each specific item exactly. I've carefully escaped all special regex characters like dots (.), plus signs (+), parentheses (()), question marks (?), square brackets ([]), and other metacharacters that would otherwise have special meaning in regex. For string literals that contain quotes, I've properly escaped those as well. The pattern will match exactly the 20 target items while avoiding matching anything else in the text.
