title: How to make SQL request to get table of counted keywords?
body: <p>I need to make a single SQL request like this:</p>
  
  <pre><code>SELECT genres, count(*) FROM books WHERE genres LIKE 'Fiction%'
  </code></pre>
  
  <p>But I need to use many keyword like 'Nonfiction%', 'Historical' ect. The output should be a table:</p>
  
  <pre><code>Fiction           8654
  Nonfiction        6543
  Historical        2344
  </code></pre>
  
  <p>What SQL request I have to use to get this result?</p>
