Open any book with text in it that includes an apostrophe spelled with smart quotes. (E.g., I discovered this using Deepening Your Ministry Through Prayer and Personal Growth.)
Ctrl+F, enter a word with an apostrophe in it; just type it normally on the keyboard, since you can't easily enter smart quotes manually (E.g., I searched for The Pastor's Sabbath, which I knew was a chapter title in that book.).
Result: It doesn't find what you're looking for.
Expect: It should match. Users shouldn't have to know the difference between apostrophe as typed on the keyboard and smart quotes. Word matches either normal or smart quotes when you search for an apostrophe. Logos should be as smart.
