The filters above are mostly dropdowns, while the ECL filter requires typing in a valid query. A content assist, which can be activated by pressing Ctrl
+ Space
, helps users to construct ECL queries easily.
Active members of a resource will only be detected correctly after the resource is synchronized, i.e. it is either released or exported to RF2.
In case of SNOMED CT, the matching search results can be sorted based on semantic tags serving as a sort of a grouping for better overview.
Once all the required filters are specified, pressing will update the tree only with the matching results according to the filters.
This sorting option can be accessed from the Content display options ().
