DataAssist stores the search into a session variable.
the naming scheme for the session variable is:
WADbSearch1_<page_name>
so if you have a named productsResults.cfm
the session will be named:
WADbSearch1_productsResults
you should see the session variable listed on the bindings panel.
while on the bindings panel, click the plus button and select URL variable, set it's name to "reset"
on the results page add a link to clear the search passing the reset qurystring variable:
<a href="productsResults.cfm?reset=true">Clear Search</a>
Now on the server behaviors panel, use the Cookies toolkit Clear Session Value behavior. click the plus button and select WA Cookies toolkit -> Clear Session values. click the lightning bolt next to triggers and select the reset URL variable.
from the list of session variables to clear, select the WADbSearch1_<page_name> session.
