I want to find patients with a MMSE score of 2 in the Mild Alzheimer's disease category within the Clinical Measures section of the BIRN Oasis database, with a specificity scale of 0 and a query timing set to ANY. The panel timing and accuracy scale are both set to ANY and 100 respectively, and the panel number is set to 1 and 2 for the two different panels specified. The query is not inverted, and there is a total of 1 item occurrence per panel. The hlevel for the first item is 3, with a key of "\\BIRN\BIRN\oasis\Clinical Measures\MMSE score", and the second item has an hlevel of 4 and a key of "\\BIRN\BIRN\oasis\Clinical Measures\MMSE score\Mild Alzheimers disease". The third item has an hlevel of 5 and a key of "\\BIRN\BIRN\oasis\Clinical Measures\MMSE score\Mild Alzheimers disease\2". All
