Whenever you are dealing with looking for the special characters in a regex (regular expression) you need to use a ‘delimiter’ to denote that it’s the literal character you want to search for, not the special meaning.
In Notepad++ we use \ as a delimiter. Thus \( means search for a literal ( (left curved bracket). If you wanted to search for () together as literals use \(\). There can be some exceptions but for clarity use \ for every special character. So even the \ is special so literally it is \\.
