title: how do i use findone in loopback.js
body: <p>I have several objects in model. I want to find by </p>
  
  <p><code>"user":"restlessankur@gmail.com"</code></p>
  
  <p>How do i do this in loopback.js? </p>
  
  <p>I tried findOne and I input </p>
  
  <p><code>{"user": "restlessankur@gmail.com"}</code></p>
  
  <p>I see result containing  <code>user:restlessankur@gmail.com</code></p>
  
  <p>But, if i filter it by <code>user:meghanetpulse7@gmail.com</code> </p>
  
  <p>even then, I get <code>"user":"restlessankur@gmail.com"</code> as result.</p>
  
  <p>So, I have 2 questions </p>
  
  <p>1) Is <code>findOne</code> correct method for my scenerio?</p>
  
  <p>2) If yes, than what I am doing wrong here?</p>
