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 (TIMEDATE) 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 146). 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 (TIMEDATE) and the Field Value is set to 07/
04/1997, the report would only include events that occurred after July 4, 1997 (see Figure
147). Events that occurred on or before July 4, 1997 would be excluded from the report.

Less Than Operator (<)
As a report is being generated, a search expression using the Less 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 less 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 (TIMEDATE) and the Field Value is set to 07/
04/1997, the report would only include events that occurred before July 4, 1997. Events that
occurred on or after July 4, 1997 would be excluded from the report (see Figure 148).
