Quotation marks should be used when searching for specific phrases or terms, as they ensure search engines only return results containing the exact words within the quotes. A general search for "dogs" will return broad results about dogs overall, while searching for "Dogs That Love Water" using quotes limits it to only pages discussing that exact phrase. Quotation marks are good for finding very precise information when you know exactly what you need to search for or want to verify a specific idea; general searches without quotes are better suited to initial exploration or gathering broad information on a topic.
