Batch Search and Print

Let's say I have a file containing 500 pages in pdf form. On each page, there is a unique order number (so 500 unique orders in total). Is there a way to run/generate a script to find multiple order numbers and then print/save them in a new file? For instance, I want to create a new pdf with only 20 orders. Is a way to run a batch "find" and print/save in a new pdf?
