+/**\r
+ * Represents a query parameter as it applies to the Pazpar2 search command\r
+ * \r
+ * <p>A query parameter can consist of a term value and/or one or more expressions \r
+ * separated by boolean operators.</p>\r
+ * \r
+ * <p>A complex query can be represented in the object as either one long string \r
+ * set by <code>setQuery(string)</code> or as a series of expressions set by \r
+ * <code>setQueryExpression(...)</code> (or a combination of the two). The difference\r
+ * between the two approaches would be the option of easily removing individual \r
+ * expressions again or otherwise treat them has separate entities in the UI.</p>\r
