I want to find all patients who have had any encounter related to the circulatory system within the specified time frame of 8:27:58 on August 25, 2023. This query will return results with a high level of specificity, considering all encounters regardless of their timing, and it will not be inverted. The query will search for the term "Circulatory system" within the given time frame and return one result. The tooltip provides additional information about the date and time of the query creation, indicating that it was created as a demo on August 25, 2023 at 8:27:58.
