3.0 Power Search Event Reports
Power search event reports allow an operator to create custom event reports by creating custom
database search expressions. These expressions are created to filter out unwanted information so that
the report contains just the desired information.
Power searches are performed on the event file stored on the host computer. The event file is a
collection of all events received from all controllers on the access control network. Each event in the file
is saved as a string of information. When generating a power search event report, the search expression
is applied to each event string and those strings that meet the search expression criteria are added to the
report.
NOTE: To successfully create custom database search expressions, the operator must have a basic
understanding of Boolean arithmetic. Boolean arithmetic is the tool used to create the custom search
expressions. This Users Guide will describe the Boolean operators used in this program, but it cannot
teach Boolean arithmetic.
To create a search expression, individual search criteria parameters are defined in the new criterion field
(see Figure 7-21) and then are entered into the search expression field to create the complete search
expression. There are five individual fields within the new criterion field. A search expression can
consist of one Field Type, Operation, and Field Value for a simple data filter. Or it can include Link
operators to combine simple expressions into complex expressions, and parenthetical operators to group
certain expressions together to perform complex data filtering.
• Field Type – The type of data for which to search.
• Operation – The Boolean operator to use to determine how to include and exclude data.
• Field Value – The value of the Field Type data for which to search.
• Link – Combines Field Type, Operation, and Field Value expressions.
• Group – Parenthetical grouping operators to create complex expressions.

This section describes the individual fields and values used to create a power search expression, and
then it provides an example of creating a complex power search.
