The “Find” tab (circled) can be used to access a function that will alphanumerically search the vocabularies. Also shown is the “Constraints” options which allows dates and special characteristics associated with the semantic type (in this case diagnoses) to be chosen. Available for diagnoses are primary/secondary/admission status of the diagnosis, and an option to search based only upon the parent code (and not the children). Also circled (towards the right) is the timing option selector.
