title: regex optional word match
body: <p>I'm trying to create a regex for extracting singers, lyricists. I was wondering how to make lyricists search optional.</p>
  
  <p>Sample Multiline String:</p>
  
  <pre><code>Fireworks Singer: Katy Perry
  Vogue Singers: Madonna, Karen Lyricist: Madonna
  </code></pre>
  
  <p>Regex: <code>/Singers?:(.\*)\s?Lyricists?:(.\*)/</code></p>
  
  <p>This matches the second line correctly and extracts <code>Singers(Madonna, Karen)</code> and <code>Lyricists(Madonna)</code></p>
  
  <p>But it does not work with the first line, when there are no Lyricists. </p>
  
  <p>How do I make Lyricists search optional?</p>
