2. If there was no data that meets the search criteria, an empty report warning window
appears (see Figure 140). Click on the OK button and modify the search criteria in the
Quick Search window.
3. If the search was successful, a Windows File Save window appears.
4. In the File Name field, enter a descriptive file name. For example, for an event report of
back door access:
• in Windows 95 it could be named "Back Door Access.txt"
• in Windows 3.11 it could be named "bkdracc.txt"
NOTE: The Windows 3.11 operating system has a limitation of no more than 8 characters for
the file name and 3 characters for the extension. The Windows 95 operating system maintains
the 3 character limitation for the extension, but allows up to 255 characters for the file name.
5. In the Folders field, locate the folder where the report file should be saved (the default is
to save it in "c:\kerisys\doors").
6. Click on the OK button and the report is saved.
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 143) 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.
