Document Grouping

- Collapse/Expand parser grouping

Experience Optimizer makes it easy to group documents together so they can be presented to the user. This can be useful when you want to show several documents that are relevant to each other, for example.

result list

Document groups can be boosted or blocked. If you want to promote a document group that is new, for example, you can boost the group to the top of the results.

You can still apply rules individually to documents within a group. This allows you to boost a document based on a specific user’s search behavior. If a user that is typically interested in ballet searches for "dance" content, you can boost ballet-related articles to the top of the group.
