Advanced Bin Search - On hand greater than zero

I'm stuck building a search to show items with quantity on hand greater than zero with the advanced bins feature on.

It only seems to fail when I use a search filter expression (which I have to use because I am using the 'OR' between expressions.

So, the following works:

var filter = new nlobjSearchFilter('quantityonhand', 'binonhand', 'greaterthan', 0);  var results = nlapiSearchRecord('item', null, filter);

But, as an expression, it fails with "Code: INVALID_SEARCH_OPERATOR Details: You need to provide a valid search field operator."

Here is what the expression search looks like:

var filter = ['quantityonhand', 'binonhand', 'greaterthan', 0];  var results = nlapiSearchRecord('item', null, filter);
