title: Oracle REGEXP_LIKE and word boundaries
body: <p>I am having a problem with matching word boundaries with REGEXP_LIKE. The following query returns a single row, as expected.</p>
  
  <pre><code>select 1 from dual
  where regexp_like('DOES TEST WORK HERE','TEST');
  </code></pre>
  
  <p>But I want to match on word boundaries as well. So, adding the "\b" characters gives this query</p>
  
  <pre><code>select 1 from dual
  where regexp_like('DOES TEST WORK HERE','\bTEST\b');
  </code></pre>
  
  <p>Running this returns zero rows. Any ideas?</p>
