Bug: filterBy resulting in duplicate entries

[kcalliauw]

Hi,

As witnessed in the following JSbin:
http://jsbin.com/liwexa/5/edit?html,js,output

When filtering on multiple fields, the search value should be null instead of an empty string. When a user types something in the search box, the filter works, but when deleting the input again, the output results in duplicate entries. The initial rendering can be fixed by initialising search as null.

Cheers,
Koen
