In the Files & Images section of the CMS there is a search input field at the top-right of the grid. It looks like this is using ajax from a dataobject_manger.js refresh() function which calls an action "/admin/assets/EditForm/field/Files" with a number of parameters such as start, limit, search, etc. Where is the actual query in the code? The ajax on success returns the entire form html, but no matter what I search, it always returns the same html which is the same html when you first come to the page, it's as if the query didn't include the search parameter.
