When you type a bunch of search terms into Google, it's smart enough to understand—more or less—what you want. However, the search engine sometimes provides results that match most of, but not all, of the words you typed. To be more specific, you can point out which keywords are the most important: Put a plus symbol (+) in front of words you want to force Google to include. What if the results you want get pushed off the page by similar, but irrelevant, articles? There's an easy fix: Just add a minus symbol (-) in front of keywords that you don't want to see.
