1. A method for asset searching, the method being implemented by one or more processors and comprising: associating each asset in plural groups of assets with one or more asset-specific content items; determining a plurality of common metadata objects, each common metadata object corresponding to one of the plural groups of assets, wherein each common metadata object is based on a set of common attributes that are associated with each asset in the corresponding group of assets; associating each common metadata object with a descriptive content buoyancy; associating each common metadata object in the plurality of common metadata objects with a common description of the corresponding group of assets, wherein the common description is distinct from the set of common attributes and the common metadata object itself; determining a search query comprising multiple asset attributes that are specified by a user; comparing the search query to (i) each common metadata object in the plurality of common metadata objects, and (ii) the common description associated with each common metadata object, to determine a search result that identifies at least one of the plurality of common metadata objects; selecting asset-specific content for display based on the descriptive content buoyancies of the at least one identified plurality of common metadata objects; and providing for display, in response to the search query, content including (i) the common description of the corresponding group of assets associated with the at least one common metadata object identified by the search result in an order based on the associated descriptive content buoyancy, and (ii) the selected asset-specific content.
