Advanced Filters

To add an advanced matches filter, select "matches (advanced)" from the filter's drop-down menu.

In the text field, enter your filter expression.

Filter Expressions

Filter expressions in ChainArgos are not case-sensitive.

To enter a special character in a "matches (advanced)" filter, first add a leading carat ^. For example, to filter on hamas, terrorist, you would enter hamas ^, terrorist.

Custom "User Attributes"

Your ChainArgos system administrator can configure user-specific values called "user attributes" that let you automatically customize a Look and/or Dashboard for each user (optional).

To reference a "user attribute" in an advanced matches filter, use the syntax {{ _user_attributes['name_of_your_attribute'] }}.

Custom "User Attributes" are a ChainArgos option, please contact ChainArgos to find out more about customizable "user attributes".
