Internal issue 3091 - Addition of grouping in search bar results

*Summary:*

Addition of grouping within search results in the search component.

*Description:*

Within the search bar component, there is currently no way to search results that have been grouped. It is possible to group these items, in a similar way to how grouping is carried out in the select components. However, when searching, only the group label can be searched for, and not the children labels. It would be good to implement this to allow for the child items to be searchable, like it is in the select component with grouping and search (See attached).

*User value:*

This would allow for a cleaner implementation of large scale searching.

*Acceptance Criteria:*

Given a user types in a search query

When there are two similarly named results in different groups

Then the results should be displayed in their relative groups.

*Urgency:*

Medium

Start with the search bar component and compare its grouping and search behavior with the select components, which already support grouped searchable items. Done means child labels can be searched and similarly named results are displayed within their relative groups.
