Some of the default SmartTarget / Experience Optimisation Triggers have modifiers/conditions on their rules.

For example, when using the Number of results Trigger, there is a dropdown with the following options:

  • is above or equal
  • is below
  • is
  • is not
  • is between

My question is whether it is possible to add these (or similar) options for Custom Triggers.

For example, I would like my rule to be: "... Where segment is not 'Control Group'"

I have the following in my trigger-types.xml:

<trigger-type basetype="text" url-param="client_segment" name="User Segment">
  <list-of-values>
    <value>Under 40</value>
    <value>Over 40</value>
    <value>Control Group</value>
  </list-of-values>
</trigger-type>

I've looked in the Defining Trigger types documentation, but cannot see this as an option.

Q1. Is it possible?

Q2. If it is possible, how is it achieved and what are the constraints?

It is not possible to define which operators are available for your trigger. It is based entirely on the basetype of the trigger type (text, float, etc.). This is a limitation of Fredhopper.

As such, the only way to choose "Segment is not 'Control Group'" would be to select every other Segment in the Promotion editing screen.

  • Thanks for the answer, Peter. That's kind of the conclusion I was coming to (with some help from Neil Gibbons). Unfortunately, sometimes the Segment will not be populated (i.e. null and no value at all), but I still want to trigger the Promotion. Therefore, in this case I think we'll need an explicit 'Not Control Group' segment.
