To search assets within a catalog, follow these steps:
Step 1. From the Catalogs tab, make sure the right catalog is selected.
Step 2. Click the Advanced Search tab.
Step 3. Specify your Advanced Search.
Step 4. Make sure the “Search within <catalogname>” check box is selected.
Step 5. Click the Search button at any time to update the search results.
NOTE: The Search field in the Catalogs panel is not an asset search. It is provided to type a catalog name to zero in on the catalog you want, useful for when there are many catalogs listed.
