If a user searches for "shoes" on a search engine "my-new-search.com", typically the search term is added in the URL like this: http://my-new-search.com?term=shoes. When a user clicks a search result on that page, they are taken to a destination site. On the destination site, the URL from the search engine will now be set in the document.referrer parameter. To register this new search engine with Google Analytics, the query parameter term must be supplied as the value for the queryParamName parameter.
