title: search:search() vs cts:search() in MarkLogic
body: <p>I have read about <code>cts:search()</code> and <code>search:search()</code> separately but could not figure out the exact difference between them. It says <code>cts:search()</code> ultimately uses <code>search:search()</code>.
  Can anyone illustrate in detail the scenario where one should go for <code>cts:search()</code> and for <code>search:search()</code>.This is not in relation to some particular project work where I need to implement this but in general.</p>
  
  <p>Thanks!</p>
