51 * Representation (e.g., Patient Name (0010,0010))."
52 *
53 * Pay attention to the fact that "*" (resp. "?") generally
54 * corresponds to "%" (resp. "_") in primitive LIKE of SQL. The
55 * values "%", "_", "\" should in the user request should
56 * respectively be escaped as "\%", "\_" and "\\".

58 * This matching must be case sensitive: The special case of PN VR
