I want to find all medication records in the i2b2 database with the exact constraint value of "test test" in the Rx Sig field, and the specificity scale is set to 0, meaning all records will be returned regardless of their relevance to the search criteria. The panel timing is set to ANY, indicating that the search is not limited to a specific time frame, and the accuracy scale is set to 100, meaning the search is highly accurate. The query name is "Medications@13:56:27", and the query timing is also set to ANY, meaning the search can be conducted at any time. The panel number is 1, and the total number of items to be searched is 1. The class of the item is ENC, and the icon is set to FA. The tooltip for the item is "Medications", providing a brief description of the query.
