How to use find to get only string sequence, not within other words

Question

How do I use the Command ⌘+F find to get only a in the text a apple, instead of highlighting both a and a in the word "apple".

Answer 1

If you search for "a " (note the space after the letter), you'll get all words that end in the letter a. You could also search for " a " which will show all the words "a" surrounded by spaces on both sides.
