Providing Search Results based on an Estimated Age of a Current User of a Mobile Computing Device

A search server that provides search results to a mobile computing device based on an age of a current user of the mobile computing device. The search server receives a search request from the mobile computing device. The search request includes a search query, and an image captured by a front-facing camera of the mobile computing device. The search server estimates an age of the current user based on the image. The search server can estimate the age of the current user by extracting one or more facial features from the image, and determine the estimated age based on the extracted facial features. Upon estimating the age of the current user, the search server can filter out search results that may not be suitable for the current user based on the estimated age of the current user. The search server can also assign lower relevance scores to search results that may not be relevant to the current user based on the estimated age of the current user.
