The default behavior of the product to search multiple values of the same custom field is to find any items which match to any of the options selected. For example, if a media item is created with the values of a custom field put as "option 1" and "option 2", and another media item is created with the same custom field having a value "option 1" only, then a user filtering the list checking both "option 1" and "option 2" in the form would see both media items in the results. With this update, we detect such cases and give users an additional selection field under the checkboxes allowing to change this behavior and find only the media items which have ALL instead of ANY selected options checked.
Also, admins are able to set if the default match type for a field should be "Match all options" or "Match any option". This can be set in add/edit field page, under the sector "Options for choice fields".
