title: Can i query a quickbooks customer by name and email
body: <p>I write a code to integrate a shopping cart with quickbooks, using quickbooks web connector. The problem is when i try to find out if there is a customer in quickbooks filtered by name and email. I tried with this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;?qbxml version="9.0"?&gt;
  &lt;QBXML&gt;
      &lt;QBXMLMsgsRq onError="continueOnError"&gt;
      &lt;CustomerQueryRq&gt;
          &lt;FullName&gt;Mladen Petrov&lt;/FullName&gt;
          &lt;Email&gt;bksi@abf.cd&lt;/Email&gt;
      &lt;/CustomerQueryRq&gt;
      &lt;/QBXMLMsgsRq&gt;
  &lt;/QBXML&gt;
  </code></pre>
  
  <p>But it returned me an error. Is there a way to find quickbooks customer by Name and email, or i have to get all the QB customers and somehow store them to my db with their QB ids?</p>
