    Ids the app keeps for one search interaction and threads across the typeahead and SERP requests (Android 450):

    • searchSessionId — one per search session, shared by the typeahead and the account_serp request;
    • typeaheadSessionId / clientUuidRankToken — one per typeahead (typing) session; the SERP response's rank_token echoes the rank token without dashes;
    • serpSessionId — one per SERP, sent as both serp_session_id and qpl_join_id.
