37        Like a primary database, you can read records from your secondary
38        database either by using the 
39            <span>
40                <code class="methodname">SecondaryDatabase.get()</code> method,
41            </span>
42            
43        or by using  
44            <span>a <code class="classname">SecondaryCursor</code>.</span> 
45             
46            
47        The main difference between reading secondary and primary databases is that when
48        you read a secondary database record, the secondary record's data is not
49        returned to you. Instead, the primary key and data corresponding to the
50        secondary key are returned to you.
51    </p>
52      <p>
53        For example, assuming your secondary database contains keys related
54         to a person's full name:

92        only return the first record found in a matching duplicates set. If you
