1. A system for generating query suggestions, the system comprising:
a database comprising a query index that includes a search tree having nodes corresponding to different queries, each of the nodes of the search tree including first temporal score(s) assigned to the respective query based on a user clicking on related link(s) when browsing retail website(s) or online retail platform(s) and second temporal score(s) assigned to the respective query based on the user adding related item(s) to a shopping cart when browsing the retail website(s) or online retail platform(s), wherein the first temporal scores are computed using different decay function(s) than the second temporal scores; and
a control circuit having access to the database and configured to:
receive a query prefix from the user;
select one or more of the queries from the search tree as query suggestion(s) for the query prefix based on a combination of the first temporal scores and the second temporal scores; and
present the query suggestion(s) to the user.
