Start a PDF search at a specific page of the document

Partly for usability reasons, partly for working around the PDF searchString memory issue with very long PDF files, I‘d like to start beginFindString: at a certain position.


The documentation points to the string search options, which is at least some pointer.


So, basically, I would have to use the NSAnchoredSearch option. However, which range to set here when I would like to start from a specific page of my document?


Thanks for any helpful hints!
