title: Regular expression ignores text "(10)"
body: <p>I am using this regular expression to find exact strings but it tends to ignore following strings,</p>
  <p>This works,</p>
  <pre><code>var textFragmentAbsorber = new TextFragmentAbsorber(@&quot;internal(?=\s|$)&quot;);
   
  </code></pre>
  <p>This doesn't,</p>
  <pre><code>var textFragmentAbsorber = new TextFragmentAbsorber(@&quot;internal (10) Ab(?=\s|$)&quot;);
  </code></pre>
  <p>By doesn't work I mean it doesn't finds the text   &quot;internal (10) Ab&quot;</p>

  <p>Text I am getting is from web services, so all I can do is add regex at end... it can be (10) or ((((( 1000 , i can't imagine</p>
