The selection of content to present to a user can be based at least in part upon probabilities of the user selecting to view more information and/or entering into a transaction with respect to instances of the content. For example, user behavior with respect to various queries provided through a content provider can be determined in order to calculate a probability that a user was searching for a particular image. The user behavior can include historical action data, such as information that indicates images associated with an action (e.g., selected, purchased, etc.) in response to a particular image search. The historical action data can be analyzed to generate an index that indicates a likelihood that the search was intended for a particular image. Once an image query is received, items of interest can be determined using the index, and those images and associated content can be presented to the user.
