Abstract: Techniques for determining search results based on session based refinements are presented herein. A method is disclosed that includes receiving a query in a user session, the query comprising one or more search parameters, detecting, in the user session and after receiving the query, a user event associated with a property of an item, updating a record in a table that associates the query with the property, the table comprising a plurality of records that associate the query with respective item properties, the record comprising the query, the property, and a score, and ranking search results for a subsequent query based on the associated properties indicated in the plurality of records, the subsequent query including the one or more search parameters.

Abstract: Techniques for determining search results based on session based refinements are presented herein. A method is disclosed that includes receiving a query in a user session, the query comprising one or more search parameters, detecting, in the user session and after receiving the query, a user event, updating, for each previous query in the user session that includes one or more of the search parameters, a record in a table for the query, the record storing a count of user events that match the user event, updating a score for each of the previous queries based on the count of user events, the respective records further storing the score, and ranking search results for a subsequent query based on the scores in the table, the subsequent query including the one or more search parameters.

Abstract translation: 本文介绍了基于会话优化来确定搜索结果的技术。 公开了一种方法，其包括在用户会话中接收查询，所述查询包括一个或多个搜索参数，在用户会话中检测并在接收到查询之后，检测用户事件，为用户会话中的每个先前查询更新， 包括搜索参数中的一个或多个，用于查询的表中的记录，记录存储与用户事件匹配的用户事件的计数，基于用户事件的计数来更新每个先前查询的分数， 相应的记录还存储分数，并且基于表中的分数对后续查询的搜索结果进行排序，后续查询包括一个或多个搜索参数。
