1. A method comprising: detecting, by a computing device, a user input for a telestration on an image being displayed on a display device; determining, by the computing device, a plurality of image portions of the image based on the telestration, wherein the plurality of image portions are determined by a boundary around each image portion based on the telestration; determining, by the computing device, a set of tags for the plurality of image portions, wherein the set of tags are determined based on image recognition of content in the plurality of image portions; determining, by the computing device, an operator based on the telestration, wherein the operator characterizes an operation to perform for the plurality of image portions; determining, by the computing device, a search query based on applying the operator to the set of tags; and causing, by the computing device, a search to be performed using the search query.
