Relation-based search and filters: Limitations and guidelines

Note Data Marketplace searches based on relations only if the Relation-based search setting has been enabled.

  • If you don't use the relations of the Stewardship operating model, the out-of-the-box relation indexes used for the relation-based search and out-of-the-box relation-based filters won't work. You will need to create custom relation indexes.
  • You cannot create more than 20 relation indexes in Data Marketplace.
  • When you create a relation index:
    • You can't use special characters in the relation index name. Only use alpha numeric characters and spaces.
      The maximum number of characters in the relation index name is 50.
    • You can't add more than four relations to one relation path.
    • Complex relations are not supported as custom relation paths.
    • You can include the following attribute types in a relation path: Text, Selection, Multiple Selection, Numbers, and Boolean (True/False). The attribute types Date and Script are not supported.
      If the attribute type included in the relation index has a cardinality higher than 1, we only show the first alphabetically sorted occurrence of the attribute as a filter option in the Data Marketplace Filters pane. This limitation applies to Selection, Multiple Selection, Numbers, and Text.
      Example 

      Attribute Multiselect can be added multiple times (cardinality is set to 2).

      In Data Marketplace, only the first alphabetically sorted occurrence of the attribute is shown.

    • You don't receive a preview of the possible relation path results if the relation path ends with an attribute.
    • HTML-tags are displayed in the preview of the possible relation path results. These HTML-tags may also appear in the filter values.
    • We recommend that you don't create relation indexes with identical relation paths. If they both show up as filters in the Filters pane, it will be confusing to your users. Currently, we don't prevent you from creating identical relation indexes.
  • Relation-based filters also show the asset type's parent as a filter option after relation reindexing.
    Example 

    You select System as the target of a relation path and show it as a relation-based filter. In that case, Data Marketplace will include the following filter values:

    • The values of asset type System.
    • The values of the child asset types of System, if any.
    • The Technology asset (because it is the parent asset type of System).
