Check if int is > 0

Hi, I have found a very strange case.

I have a table with an integer field called quantity and I would like to search with $fieldSearchable only if is > 0.

This is my code for $fieldSearchable inside my model

```
protected $fieldSearchable = [
'quantity'=>'>'
];
```

Into my database I have two records: one with quantity 2 and another with quantity 0

If I try to make this request:

`?search=1&searchFields=quantity
`
returns me the first array correctly

If I make this request:

`?search=0&searchFields=quantity`

returns me the first and the second record! But I'm expected to return only the first with quantity 2 not the second with quantity 0
