<p>The <code>%like%</code> function:</p><ul>
<p>This <code>%like%</code> function:</p><ul>
<li><p>Is case-insensitive (use <code>%like_case%</code> for case-sensitive matching)</p></li>
<li><p>Supports multiple patterns</p></li>
<li><p>Checks if <code>pattern</code> is a regular expression and sets <code>fixed = TRUE</code> if not, to greatly improve speed</p></li>
<li><p>Checks if <code>pattern</code> is a valid regular expression and sets <code>fixed = TRUE</code> if not, to greatly improve speed (vectorised over <code>pattern</code>)</p></li>
<li><p>Always uses compatibility with Perl unless <code>fixed = TRUE</code>, to greatly improve speed</p></li>
