title: ARCGIS Javascript Need to select all feature in map
body: <p>I am using ArcGIS Javascript language, and using esri.tasks.FindTask, i wanna select all the features.</p>
  
  <p>When i am passing the blank parameter than it is not working.
  I am pasting some code. In this code i have searchid and seachField than execute method will call.</p>
  
  <pre><code> var searchText = document.getElementById('txtSearch').value;
          findTask = new esri.tasks.FindTask(SearchURL);
          findParams = new esri.tasks.FindParameters();
          findParams.returnGeometry = true;
          findParams.layerIds = [searchId];
          findParams.searchFields = [seachField];                             
          findParams.searchText = searchText;
          findTask.execute(findParams, showResults);
  </code></pre>
  
  <p>but if suppose i will pass blank value in searchtext that time and it is not giving me any feature.   </p>
  
  <p>Any idea ...Thanks in advance</p>
