title: MongoDB $near with encrypted gps data?
body: <p>I'm trying to use MongoDB <strong>$near</strong> function with user GPS(Location) data.</p>
  
  <ol>
  <li>MongoDB doesn't support DB encryption. </li>
  <li>Therefore, if i want to encrypt data, encrypt data on the client side.</li>
  <li>In that case, I cannot use $near function.</li>
  </ol>
  
  <p>Q1. How can I use $near function in encrypted data?</p>
  
  <p>Q2. In U.S. user GPS data must have encrypted?</p>
