I want to find records where the external causes code (PrevQuery)External causes@23:41:16 is present and the assault by crash code (PrevQuery)Assault by crash@19:55:01 is also present. The search will include any timing and the specificity scale is set to 0, meaning the search will return all records where both codes are present regardless of how specific the information is. The panel accuracy scale is set to 100, indicating that the search will return the most accurate results. The invert flag is set to 0, meaning that the search will return only records that match both specified codes.
