How to speed up the OCR scanning progress?

thanks @vvaidya~

if I would like to specify page 1 and 4, how should I express it? “1” + “4”?

further, if I would like to read OCR in PDF, say:
Date of Issue: “22 Nov 2016”, shall I use “set focus” to highlight the “Date of Issue” and how can I read “22 Nov 2016” in UIPath?

Further, may I know how to identify a PDF, say when PDF pages more than 5 pages.? coz usually my PDF only contain less than 4 pages, so how can I express in UIPAth that if more than 5 pages, this is special PDF?

much appreciated and thanks~
