A search will be made of the item name, description and tags but you can widen the search to also include resources, panel data and attributes.
Ticking the panel data option will widen the search to include all panel data.
Ticking the resources option will widen the search to include all resources (names, descriptions and tags).
Ticking the Include All Attributes option will widen the search to include all attribute names.
The peek button on each item in the list can be used to review the content of the item to help you find the item you were after, which you can also edit whilst in peek mode. You can scroll left and right through the items in the search list, then exit peek mode back to the search results.
Clicking on an item in the search results opens the item in edit mode and exiting returns you to the starting view not the search results.
