description A method and system to index and search item listings in a network-based publication system, such as a network-based marketplace. For example, a listing query may be received from a user, the listing query including a query image. The query image may then be processed to generate a plurality of index sets. Each index set of the plurality of index sets may correspond to a respective portion of the query image and may comprise a set of index values. Each index value of the set of index values may be indicative of an image attribute, such as light intensity, for a respective sub-portion of the corresponding portion of the query image. At least one result image from a database of listing images may be identified by comparing the plurality of index sets for the query image to pre-compiled index sets in an index database. Each pre-compiled index set may be associated with at least one listing image which, in turn, may be associated with an item listing on a network-based marketplace.
