Grouping search results

When records with same title and same author are found in multiple formats (media types), they can be grouped automatically. For example, if a title is available in book format and ebook format, the results can be grouped, showing one of the formats with an Extend button beneath.

The search results can also be grouped parent-child. For example, the CD title is a parent and all tracks on the CD are children.

To group the search results: The configuration setting Page option: Show enhanced data is used. In that dropdown, select the option Grouped results: Grouping matching data.
To decide what to group in a search result: The configuration setting Grouped results: group field is used (for setting definitions, see above).
When you want to group parent-child records, you set how you want to group them using the configuration setting Show linked records (for setting definitions, see above).

Sorting within a group

The following settings are used for the appearance within the groups:

Grouped results: sort field
Grouped results: sort order within list
Grouped results: Max number of titles grouped
