When you have more than one condition in a search, you must decide if all conditions must be met (AND) or only one of them needs to be met (OR) for a document to qualify. You can also build more complex conditions by nesting groups of conditions. For example, you can indicate that conditions A and (B or C) must be true. Thus, a document would qualify if A and B are true. A document would also qualify if A and C are true. If A is not true, the document would not qualify.
You can specify AND or OR for two or more contiguous rows. Thus, rows must be arranged so that you can group them appropriately. In the previous example, rows B and C must be contiguous so they can be grouped by OR. Row A can be above or below the OR grouping.
By default, all conditions are initially linked by AND. If you find that you use OR most of the time, you can change the default to OR in the Search Designer options. This change lasts only for the current session.
To specify AND or OR within a grid:If your requirements change after you enter the rows, you can move one or more rows from one position to another position.
Using the previous example, if you wanted to link Content Size and Creator with OR and link those to Date Created with AND, you would need to cut Content Size. Then you would highlight the Date Created row, click the Insert a Row icon, and paste into the blank row. You would also need to re-specify the AND and OR operators.
