I want to find all instances of the "Family history" report within the "Medical History" section of the i2b2 database, where the text "age" is mentioned or included in the report content, and the timing is set to ANY, meaning the search is not restricted to a specific time frame. The specificity scale is set to 0, indicating that any mention of "age" within the report will be considered, and the panel accuracy scale is set to 100, indicating a high level of confidence in the results. The query is not inverted, and only one item is being searched. The hierarchy level is set to 3, and the class is set to ENC (Encounter), indicating that the search is focused on encounter-related information.
