Less Than or Equal To (<=)
As a report is being generated, a search expression using the Less Than or Equal To operator examines
each data string in the event database, searching for data strings that meet the search expression’s Field
Type.
If the Field Type is a match, the Field Value in the data string is then compared with the Field Value in
the search expression. If the value in the data string is less than or equal to the value in the expression,
the data string is included in the report; if not, it is excluded from the report.
For example, if the Field Type is set to Date and the Field Value is set to 07/04/1997, the report would
only include events that occurred on or before July 4, 1997 (see Figure 7-24). Events that occurred after
July 4, 1997 would be excluded from the report.

Greater Than Operator (>)
As a report is being generated, a search expression using the Greater Than operator examines each data
string in the event database, searching for data strings that meet the search expression’s Field Type.
If the Field Type is a match, the Field Value in the data string is then compared with the Field Value in
the search expression. If the value in the data string is greater than the value in the expression, the data
string is included in the report; if not, it is excluded from the report.
For example, if the Field Type is set to Date and the Field Value is set to 07/04/1997, the report would
only include events that occurred after July 4, 1997 (see Figure 7-25). Events that occurred on or before
July 4, 1997 would be excluded from the report.
