AND and OR logical operators
A logical operator is a way of comparing two or more values. You use logical operators to refine your document search.
The AND logical
operator means that a document must satisfy all search values to be
included in the search results. For example, value1 AND value2 AND
value3
requires that each document returned contain all three values.
Documents containing two, one, or none of the values are not returned.
The
OR logical operator means that a document must satisfy at least one search
value to be included in the search results. For example, value1 OR
value2 OR value3
requires that each document returned
contain at least one of the three values, but not necessarily all three.
Note: Even when you choose the OR logical operator, the Date Segment field is always included with the rest of the search fields.
