title: How to use iLike operator with Sequelize to make case insensitive queries
body: <p>I am using Sequelize along with PostgreSQL in managing my database.<br>
  I would like to perform a case insensitive search query. When I googled it up, some people said that I can use "iLike" operator to do so. I tried to implement this way:</p>
  
  <pre><code>var getRadiosByGenre = function(Radio,Genre,genreName){
      Genre.findOne({where:{name: { $iLike: genreName}}})}
  </code></pre>
  
  <p>where genreName is a string.
  But, I keep getting this error:</p>
  
  <blockquote>
    <p>Error: Invalid value { '$iLike': 'art' }</p>
  </blockquote>
  
  <p>Does anyone know the correct way of using iLike with sequelize?
  Thanks mates(s). :)</p>
