A server system receives a visual query from a client system distinct from the server system, performs optical character recognition (OCR) on the visual query to produce text recog nition data representing textual characters, including a plu rality of textual characters in a contiguous region of the visual query, and scores each textual character in the plurality of textual characters. The server system identifies, inaccordance with the scoring, one or more high quality textual Strings, each comprising a plurality of high quality textual characters from among the plurality of textual characters in the contigu ous region of the visual query; retrieves a canonical document having the one or more high quality textual strings; generates a combination of the visual query and at least a portion of the canonical document; and sends the combination to the client system.
