Context
Currently the search results will be rendered using the getAllRefsInReflistOrder in MWGroupReferences. MWGroupReferences builds an index for refs and subrefs using mainRefKey. That needs to change. We need to do something similar but with the mainListIndex only.
Task
- Figure out how that list could be rendered with the mainListIndex
- Think about if we want to have a fallback for a period of time
- Use the new method or the method with fallback to render the list
