is among the words AND find words

[Jim Hurley]

Think I will try something like this.

Test to see if the word, as a string, is in the text.
If so, then strip out all characters not between "a" and "z" or "A" and "Z"  and then check to see if the stripped-down word is the same as the test word.

That way I will find "time" even if it appears as "(time)" or "time." or "time," or with quotes on either side, etc.

I wonder what algorithm LC uses in "Find word(s)" to find only words.
