Select the Target data structure in the array aggregator, map the entire array directly into the field.
Every result (item/record) from a search/match module will output a bundle. To “combine” them into a single structure, you’ll need to use an aggregator of some sort.
Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module.
The Array Aggregator module also allows you to build a complex array of collections for a later module’s field to map multiple items (collections) to it.
Here is an example of using the “Target structure type” of an Array Aggregator module:
As you can see, the “Map” toggle on fields are used when you have an array. You can easily build an array variable to map to a field, by using an Array Aggregator module and select the “Target Structure Type” as the future field you want to map the array into.
