A computer-implemented technique of providing relevant search results to a user of a website at a query time. The technique can include receiving, at a computing device having one or more processors, a query from the user, the query corresponding to a description of potential search results desired by the user. The technique can further include retrieving a user history corresponding to previous user interactions with the website and determining a context of the user corresponding to an interaction of the user with the website at the query time. The relevant search results can be determined based on the query, the user history, and the context of the user and a prediction model, and be provided to the user via updating of a webpage presented to the user. The technique can further include adapting the prediction model based on a prediction event and set of corresponding prediction event features.
