Another "tip" for searching....type-in as few words as possible as the sub-set of what you are looking for...
for example if you wanted "camera resettings" it may come up empty/nothing found....but try "rese" or "cam" and you might find little or too much...then home in on your best word size. And if still failure....try every word you can think of that relates to your search....like: view, see, find, fix, return, home, etc.
Of course I try to start with the Index or Table of Contents for the item...or at least to find the "key" words the programmers used so as to make my searches better....as often the answer is not found in the logical index or contents chapter.
Also note....for most (but not all) cases...the search tool highlights to found word in a color...so if page is long, scroll until you see the word highlighted...and there could be several on one page.
