title: How do I use ItemFilters with eBay::API::Simple::Finding?
body: <p>I am playing with getting sold items from ebay using <a href="https://metacpan.org/pod/eBay::API::Simple::Finding" rel="nofollow noreferrer">eBay::API::Simple::Finding</a> and I want to use ItemFilters but I can't see where they go. 
  In particular I am looking to use the item filters</p>
  
  <pre><code>(itemFilter.name = SoldItemsOnly, itemFilter.value = true)
  and
  (itemFilter.name = Condition, itemFilter.value = Used)
  </code></pre>
  
  <p>I tried just including directly with the following here: </p>
  
  <pre><code>keywords =&gt; '"princess cut", "diamond ring", -"14k*"', 
  Condition =&gt; 'Sold',
  SoldItemsOnly =&gt; 'true', 
  sortOrder =&gt; 'PricePlusShippingHighest'
  </code></pre>
  
  <p>I have been on it quite a while and whilst I am sure it is somehow quite straight forward, I just can't seem to get it</p>
  
  <pre><code>use eBay::API::Simple::Finding;
  
  my $api = eBay::API::Simple::Finding-&gt;new( {
     appid   =&gt; 'APIKEY',
     siteid  =&gt; 'EBAY-AU',
  } );
  
  $api-&gt;execute( 
      'findCompletedItems', { 
      keywords =&gt; '"princess cut", "diamond ring", -"14k*"',  
      sortOrder =&gt; 'PricePlusShippingHighest',
      } 
  );
  
  if ( $api-&gt;has_error() ) {
     die "Call Failed:" . $api-&gt;errors_as_string();
  }
  
  my $dom  = $api-&gt;response_dom();
  my $hash = $api-&gt;response_hash();
  </code></pre>
  
  <p>Any help is very appreciated,</p>
  
  <p>As for what I am seeing?
  The sort is working, the search by keywords is working, but the itemfilters are not working, so it is returning new &amp; used items that have completed, whether sold or unsold</p>
