    Param Type Details

    Name of the platform (Required if not using data attribute).
    query string

    source-field string

    Name of a primary field to facet on (for example "Country"). The values of this facet will define the set of graph nodes with outgoing edges. (Required if not using data attribute).
    target-field string
