There are three choices for how the search rules you create can pass or fail for this segment

{% hint style="info" %}
**All**

Every rule has to be true. If any of your rules contain false criteria, all of the rules will fail and 0 matching contacts will be returned. 
{% endhint %}

{% hint style="info" %}
**Any**

If any rule is true, return matches and simply disregard non-matches. 
{% endhint %}

{% hint style="info" %}
**None** 

Exclude contacts matching these rules from the segment
{% endhint %}
