Complex searches can also be performed, using Search - New first, then Search - Expand/Or, Search - Shrink/And, or Search - Invert/Not.

For example, to find all customers in states 'NSW' or 'QLD', enter 'NSW' in the State field, then click Search - New; click File - New to return to a blank Customer Maintenance page; then enter 'QLD' in the State field, and click Search - Expand. All customers in either of those two States will now be listed. (You may need to enter different State codes to test this, depending on what data you entered into the State class, and into the Customer class.)

You could further refine the results of the above search, to only show customers with a surname of SMITH, by entering [SMITH in the Name field, then clicking Search - Shrink.

Please note that an Expand search is equivalent to an Or search (ie 'data that matched previously or matched this time'); a Shrink search is equivalent to an And search (ie 'data that matched previously and matched this time'); and an Invert search is equivalent to a Not search (ie 'all data that did not match last time').
