thank you for offering to help. the functionality should behave like this...
you can input terms or tag words and the program will search through a pdf manual to find the pages or sections that contain those words or tags. it will present a list of found pages and the user selects which page is shown.
i don't know if i need the pdf manual to be locally within the app or if it can be in a cloud host like dropbox or google docs.
i had the interface figured out and realized i had no idea how to search the pdf manual.
if this is not clear enough, or you need more specific information, please let me know.
and thank you once again.
