@Barmar So does it search for that and also a number between 250 and 255 as well? Because someone else commented that it searches a number between 250 and 255 so idk if they're wrong or – user19106127 May 13 '22 at 00:50

2They're just two ways of saying the same thing. They described it numerically, I described it as text. – Barmar May 13 '22 at 00:51

Note that it will match anywhere in the input text. So it could be part of a longer number, e.g. if the input is `12503` it will match the middle 3 digits `250` – Barmar May 13 '22 at 00:53
