# Filters

Filters allow customizing the reports representation according to your requirements. Beside the data display convenience, filters allow detailing the reports according to your needs:

- If you use CNStats for several sites, you may generate reports for each of them separately;
- Any report can be generated for a particular country or a city (for instance, only for Russia);
- Any report can be generated for users working with Opera browser etc.
- Any other samplings in various combinations.

## Types of filters

There are the following types of filters:

- Common - the filters present itself one or more conditions, united by the same logic (and/or).
- Temporary - there can be only one temporary filter in the system. Upon logging off the filter is deleted automatically.
- By data dictionaries - standard set of filters. These filters can not be deleted or changed. The filters are generated on the basis of data dictionaries; therefore, it is possible to change filters contents on the spot upon updating data dictionaries.
- Combined - these are combination of common and data dictionary filters. Combination logic may be any.
