To search for assets with multiple criteria, add a search chip for each element of your search by using the filters or short keys.
Example: You want to find all assets with a Select and 5-star rating from a specific folder structure, see below.
NOTE: Be sure to match All the rules to return only assets with that meet all search criteria. Match Any to return assets with either 5-stars or Selects
Individual search chips can be removed while keeping the rest of the criteria. Simply click X to remove the chip and click the blue arrow to redo the search.
