Parameters

Param Type Details
platform string

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

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

Name of a secondary field to facet on (for example "City"), for every facet value of the primary field. The values of this facet will define the set of graph nodes with incoming edges. For example, say the primary facet (source-field) has values for Country=Germany and Country=France and the secondary facet (target-field) has values for City=Berlin, City=Munich and City=Paris. Then we add graph edges Germany-->Berlin, Germany-->Munich and France-->Paris. (Required if not using data attribute).
