Finding and Replacing Text
Whole Word Match
By default, the search finds any occurrence of the text that you type into the Find what field. For example, if you enter the, the search finds the word the, as well as those letters embedded in other words, such as others and theater.
If you want the search to find only whole word occurrences of the text you type into the Find what field, click the Match whole words only box in the Find dialog box.
