Advanced Search

Snowray provides an advanced search option for SNOMED CT, which can be invoked by pressing the advanced filter icon in the search bar. This enables users to specify additional criteria to restrict their searches.

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.

Once all the required filters are specified, pressing will update the tree only with the matching results according to the filters.

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.

Search results

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.

Semantig Tag Based Sorting

This sorting option can be accessed from the Content display options ().
