• 1 Required if you are using response signals.
• 2 Required if you want to weight types differently.
• 3 Required if you want to use time decay.
• 4 Required if no session_id field is available. Either user_id or session_id is needed on response signals if doing any click path analysis from signals.
• 5 Required when identifying trending queries instead of trending items.

The fields mentioned above are defined as follows:

Field Name	Example Value	Description
count_i	1	Number of times an interaction event occurred with this item
doc_id	NMDDV	Product ID or Item ID
query	xwearabletech	A query string from the user
session_id	91aa66d11af44b6c90ccef44d055cf9a	Id for session in which user generated the signal
type	quick_view_click	Type of session the user used to interact with the platform
user_id	11506893	ID of user during the session
timestamp_tdt	2018-11-20T17:58:57.650Z	Time when signal was generated

Some signal types, including custom signal types, may include additional fields.
