Hi KurtCode
I have the library with different PDF files, and it does often place the search marks wrong. In my fork, there is a PDF file called amazon-dynamo-sosp2007.pdf. Searching for the string "re" will show you that the position of the marks a sometimes calculated wrong, since they are misplaced. The same goes for the string "in" and probably others.
Is this something you might be able to fix?
Have a great day
Regards,
Kenneth
