9. A computing device to provide a metadata based search in an e-reader environment, the computing device comprising: a memory configured to store instructions; and a processor coupled to the memory, the processor executing an e-reader application in conjunction with the instructions stored in the memory, wherein the e-reader application is configured to: determine search terms based on a selected portion of displayed content; generate a query for a search based on the selected portion; determine the metadata associated with one or more objects, wherein the one or more objects include embedded images, embedded graphical objects, and one or more interactive objects, interactive puzzle objects, embedded video objects, and embedded audio objects; perform optical character recognition on each of the embedded images and the embedded graphical objects to retrieve textual content and key terms from each of the embedded images and the embedded graphical objects; index the metadata, wherein the metadata includes the textual content and the key terms; augment the query based on the metadata, wherein the metadata is associated with one or more attributes of each of the one or more objects and includes at least one from a set of dimensions, types, titles, and tags of the one or more objects; categorize a summary of query results based on the metadata; and present the summary of the query results in a results pane on a user interface.
