A method of selecting and presenting content based on detecting an increased level of activity associated with the content is presented. The method includes providing a set of content items with associated descriptive terms. The method includes receiving user search input for identifying desired content items and, in response to the incremental input entered by the user, presenting a subset of content items to the user. The method further includes receiving actions from the user selecting content items from the subset and analyzing the descriptive terms associated with the selected content items to detect an increased level of activity for descriptive terms associated with the content items selected by the users. The method includes, in response to receiving subsequent user search input, selecting and ordering a collection of content items based on promoting the ranking of content items associated with descriptive terms that have an increased level of recent activity.
