Relation-based search and filters: Limitations and guidelines

• 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 can't create more than 20 relation indexes in Data Marketplace.
• When you create a relation index:
  • You can't use special characters like / ? @ [ } in the relation index name.
  • You can't add more than four relations to one relation path.
  • Complex relations are not supported as custom relation paths.
  • Only text attributes can be selected as attributes in a relation path.
  • 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.
  • 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 that you create 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 values as filter options:

  • 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).
