The find value is a text value, so, even if it was a list of numbers, you would have to loop through the list, forcing it to read OCR each time. To make this faster, let's reduce the number of times we may have to use OCR to 2.

"Extract Text using OCR", use "Recognize entities in text: Entity Type: Number" and then compare the number to your range. If found, then have the "Find" equal the number found in Recognize Entities.

Good luck!

I assume you are doing this via the Move mouse to text on screen (OCR) action or the Wait for text on screen (OCR) action. In either case, there is a toggle called "Is regular expression". If you enable that, you can use regular expressions in the "Text to find" action. The following regular expression will match any number between 90 and 120:

(9[0-9])|(1[0-1][0-9])|120

thank u for your reply in my flow i use if text is on the screen (OCR) so if i toggle regular expression button on and copy write this (9[0-9])|(1[0-1][0-9])|120 for text to find will it search for numbers between 90-120? and i have one more question is it possible to use spesific charachters like + in the text like if its 120 i dont want ocr to find it if its +120 i want so is it possible?

Yes, the expression has some OR operators, as that is the best way to cover the range.

9[0-9] covers 90-99, 1[0-1][0-9] covers 100-119 and then there's 120 separately.

If you want to exclude cases when it's +120, you need to add a negative lookbehind to it. Use this as the regex instead:

(9[0-9])|(1[0-1][0-9])|((?<!\+)120)

It follows the same pattern, but only includes 120 if it doesn't follow a +.

Can you share what the screen looks like when it finds it?

I would also suggest using Extract text with OCR using the same settings, to see what it extracts, so you can review the actual results of the OCR search and see if there is something being misinterpreted.
