1.3. Full-Word Wildcards

Some search engines support a technique called stemming. Stemming is adding a wildcard character—usually * (asterisk) but sometimes ? (question mark)—to part of your query, requesting the search engine return variants of that query using the wildcard as a placeholder for the rest of the word at hand. For example, moon* would find moons, moonlight, moonshot, etc.

Google doesn't support explicit stemming. It didn't used to support stemming at all, but now it implicitly stems for you. So, dietary will yield results for diet, diets, and other variations on the theme.
