Browsing Assets

Once DAM installed and assets documents created, a new search type is displayed in the left menu, the Assets search. This search will let you search by assets metadata, such as:

  • Type
  • Format
  • Width
  • Height
  • Etc.

The Assets search leverages Elasticsearch to provide a quicker and more efficient search. The search form uses Elasticsearch aggregates for most fields: aggregate fields values are filtered so as to display only relevant values and show the count of matching documents for each value.

The Assets search form offers several search criteria, that you can associate to define your search and find documents. Search results use the thumbnail view by default. Clicking on a document thumbnail will lead you directly to the document.

To search documents using detailed criteria:

  1. Click on the Assets tab.
  2. Fill in the form with your criteria and/or select the search criteria corresponding to your needs.
    The search results will be automatically updated according to the criteria selected.
