Searching the manual

Is there a way to search for a phrase in the official manual? For example, if I enter the search term duplicate timeline I get results for every instance of the words "timeline" and "duplicate" but nothing for the phrase duplicate timeline.Using a Boolean operator-AND-does not work, either.

Perhaps enclosing "duplicate timeline" in double quotes would help on your system.

I have to say that I have no issue with phrase searching on my system w/o using quotes. I'm opening the manual as PDF with Adobe Acrobat Reader DC and Ctrl F to open the search.
