This page allows you to build more complex queries against the database using a preset selection of query forms and the boolean operators "AND" and "OR". For example, to construct a simple query begin by clicking on the "AND" button. Then use the pulldown menus to select two different queries. Finally, click on "proceed to next step" to generate a page that will allow you to specify parameters for the two queries. Running the resulting boolean query will return only those objects that satisfy query 1 AND query 2.
Please note: you must select a query from each pulldown menu before the "proceed" button will work. If you need to back up a step, use the browser's "back" button.
