Filters are specific rules applied to the fields of your selected data sources to segment and refine your target audience.

## How it works

You apply filters in the **Selection Criteria** step by dragging a field from the **Available Fields** section into the** Filters** section. Once added, you can choose from a wide variety of filter types to evaluate your data, such as *Equals*, *Contains*, *Is empty*, or dynamic date filters like *In previous* and *In next*. There is no limit to how many filters you can create. 

For more complex segmentation, you can combine multiple filters into groups and define their relationships using *AND* and *OR* logical statements. To save time on recurring campaigns, administrators can also configure [Filter Sets](docId\:COQ3dCJPoHJi-5W8fNyFl), which act as reusable, predefined collections of filters that can be dragged and dropped into a Selection at once.

Unaric Segment is not case-sensitive in the filter values used inside a Selection. For example, the words *Value* and *VALUE* are treated as equals.

## Filter Data Extensions

1. In the Input step, Configure the Data Extensions you want to work with and click on **Filters **to open the Filter Section.
2. Select a field from the Available Fields section that you would like to filter on.
3. Drag-and-drop it to the right, to the Selected Fields section.
4. Choose filter criteria.
5. You can group filters by hovering the **+** icon, which will indicate which filter lines will be grouped together when clicking. Don't forget to set the **AND **/ **OR** criteria for your filter grouping.
