A good example for what I mean with the header names is e.g. the datasheet of a microcontroller. For e.g. the Atmega328p, that’s a PDF with a few hundred pages.
If you search for a section explaining a feature, and you CTRL+F for the name of the feature, which is the headline of the corresponding section, you will get matches for the same exact string of characters all over the document: first in the feature list in the beginning of the document, then on the pinout, then in the text of any other feature that references the feature you are looking for, then in the appendices and lastly in the glossary. Somewhere in the middle of these potentially 100s of matches will be the correct one.
After a while of using that document, you will have the most important page numbers memorized.
