One query could have one or more criteria, they establish the connection between them by logic operators OR and AND. They add complexity to the query and make restrictions with different criteria, or the outcomes will carry out with some of the selected criteria.

Note: The set of criteria that are part of a row are a single criterion. Therefore, if you select coverage, a percentage and a surface, this set is a single and indivisible criterion of a query. If you want to add one restriction which complies with a cover, or an attribute, or a percentage or surface all of them independents, it is necessary adding four rows (one row per column) with value at the link field of OR Operation.

To indicate an operator, click on the edit key and enable one option of the verification box. True is an AND operation, False is an OR operation, the last value is established by default.
