body: <p>On the Couchbase documentation </p>
  
  <p><a href="https://docs.couchbase.com/server/6.0/n1ql/n1ql-language-reference/patternmatchingfun.html" rel="noreferrer">https://docs.couchbase.com/server/6.0/n1ql/n1ql-language-reference/patternmatchingfun.html</a></p>
  
  <p>I saw that:</p>
  
  <pre><code>REGEXP_CONTAINS(expression, pattern)
  Returns True if the string value contains the regular expression pattern.
  
  REGEXP_LIKE(expression, pattern)
  Returns True if the string value contains the regular expression pattern.
  </code></pre>
  
  <p>Is there any difference between this functions or one is an alias for another?</p>
