What’s the difference between using parentheses and quotation marks in Boolean Search?

In Boolean search, quotation marks (" ") are used for exact phrase matching. This means the search engine will only return results where the words appear in the specified order, exactly as typed within the quotes. For example, "content marketing" will only find results with that exact phrase. Parentheses ( ) are used for grouping multiple keywords or operators to control the order of operations in a complex search query. This allows you to combine OR statements with AND statements effectively. For instance, (SEO OR "search engine optimization") AND blog would find results containing either "SEO" or "search engine optimization" and also the word "blog." The options stating they are interchangeable or misrepresenting their functions are incorrect because each symbol serves a distinct purpose in refining search queries.
