Summary Section
Besides the table with the main content, a Summary Section also provides useful information such as the number of mapped members or that of unmapped members.
Member Filter
A filter bar enables narrowing down the displayed members based on the entered search term. You can search for terms, IDs, or even member IDs using the search filter.
Target Code System Filter
In case of mapping source codes to target codes from multiple different Code Systems, the Target Code System filter allows you to restrict the mappings to one Target Code System, providing a better overview of the members. When clicking in the filter bar, the default Quick Search widget displays ten options.
These can be expanded with the Ctrl+4 shortcut to show more or alternatively, you can search for a specific Target Code System using the search functionality of the filter.
The filter also provides two special options: UNMAPPED and UNKNOWN. The former filters for mappings without a target, while the latter lists mappings where the Target Code System is one that is not available in Snow Owl.
These two options are always displayed in the default Quick Search widget. The rest of the displayed Target Code Systems are listed in alphabetic order.
You can set the table preferences of the Mapping Set Editor to display or hide columns. The following information can also be displayed in the editor:
