In Kaspersky Security Center 15.1, you can apply the extended filter format to a report template. The extended filter format provides more flexibility in comparison with the default format. You can create complex filtering conditions by using a set of filters, which will be applied to the report by means of the OR logical operator during report creation, as shown below:
Filter[1](Field[1] AND Field[2]... AND Field[n]) OR Filter[2](Field[1] AND Field[2]... AND Field[n]) OR... Filter[n](Field[1] AND Field[2]... AND Field[n])
Additionally, with the extended filter format you can set a time interval value in a relative time format (for example, by using a "For last N days" condition) for specific fields in a filter. The availability and the set of time interval conditions depend on the type of the report template.
