Hazel reading only first page of pdf?

Hi,
I am new to Hazel but have already found a range of uses that really help my workflow. For instance, I am an academic and want to automate import of references that I download online or from emails (or from wherever) to Bookends. I have already managed to get Hazel to check if downloaded files in Downloads are pdfs and if their contents include a DOI-number (which almost all scientific papers do). Hazel then show the file in Finder so I can check and assign a tag, before Hazel move the tagged file to a watched import folder of Bookends, which does the rest. Voilà!

However, to make Hazel even more accurate I would like to only check for a DOI-number on the first page (which almost all scientific papers have), and not the entire document. Is there a way to limit the contents check to the first page?

Thanks on beforehand!

There's nothing like that now. Maybe there are some commandline programs that might selectively extract text by page which you can tie into a script but I don't know of any off hand.

Thanks for the quick reply! I will have a look around. It works like it is, but it could be even better with such functionality. I also realise that learning to use scripts would really expand the utility of Hazel.

Thanks again!
