Configure Related Searches web part

There isn't alot of documentation around Related Searches web part. This web part seems be related to populate suggestions dictionary. It can be populated initially from a static list of values. Then click-through will continue to add values to this list (when the same value has been entered 6 or more times). 

 

Use this link to see how this can be tested.
