title: filter functions problem
body: <p>I'm working on a search component for an app I'm working on and I needed to add some filters to it. I've found an example and got the first filter working fine.</p>
  
  <p>Now I'm trying to add a second filter I'm running into problems... In the example I found they use filterFunctions, but I only get an option for filterFunction, why is that?</p>
  
  <p>Here's the example code</p>
  
  <pre><code>   productsCollection.filterFunctions =
  [
   filterByPrice, filterByType,
   filterByCondition, filterByVendor
  ]
  </code></pre>
  
  <p>And this is what I'm trying</p>
  
  <pre><code>acData.filterFunction = [filterByStatus, filterByDate]
  </code></pre>
  
  <p>but with this code I get the following error message - 1067: Implicit coercion of a value of type Array to an unrelated type Function.</p>
  
  <p>Why am I getting this error and how would I go about add multiple filters to my Array Collection?</p>
  
  <p>Thanks!</p>
