6. A method performed by at least one computing device, the method comprising: obtaining an input search query from a user, the input search query comprising an input search term; identifying instances where other users have used the input search term in other search queries and added additional search terms to the other search queries to obtain refined search queries, wherein the refined search queries were previously entered by the other users; organizing the refined search queries that were previously entered by the other users into at least multiple first refined search queries associated with a first topic and multiple second refined search queries associated with a second topic; estimating a first relative likelihood that an intent of the user matches the first topic; estimating a second relative likelihood that the intent of the user matches the second topic, the first relative likelihood being greater than the second relative likelihood; and causing the multiple first refined search queries that were previously entered by the other users to be displayed on a graphical user interface (GUI) concurrently with the multiple second refined search queries that were previously entered by the other users, the multiple first refined search queries being displayed relatively more prominently than the multiple second refined search queries to show that the first relative likelihood that the intent of the user matches the first topic is greater than the second relative likelihood that the intent of the user matches the second topic.

The method of claim 6 , wherein: the estimating the first relative likelihood comprises tracking first instances where the multiple first refined search queries were used as first final queries by the other users to culminate corresponding first searches; and the estimating the second relative likelihood comprises tracking second instances where the multiple second refined search queries were used as second final queries by the other users to culminate corresponding second searches.
