Snowray provides an advanced search option for Custom Code Systems, 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 Status can be filtered using the radio buttons, while the ECL filter requires typing in a valid query using an improved version of SNOMED CT Expression Constraint Language that allows any kind of identifier to be used, not just SCT IDs. A content assist, which can be activated by pressing Ctrl + Space, helps users to construct ECL queries easily.
The ECL evaluation of non-SNOMED CT terminologies supports the following basic operators: =, <, <<, <!, ^, *, AND, OR, MINUS
Once the required filters are specified, pressing will update the tree only with the matching results as per the filters.
