Abstract: Devices and techniques are generally described for regionalizing content based on the availability of similar content. In some examples, a first search query related to a first item may be received. A determination may be made that the first search query is associated with a first region. In some examples, the first item may be determined to be associated with the first region based at least in part on at least one of the first item or items classified as substitutes for the first item being available in a plurality of regions. A first plurality of search results associated with the first region may be determined. In further examples, code may be generated to cause the first computing device to display the first plurality of search results.
