Abstract
Conducting a search for both text and images includes receiving input, which may include one or more search criteria for at least one of searchable image characteristics and text terms. The received input may be compared with searchable image characteristics and text terms that have been indexed in a single format for multiple stored images and text segments. A search result is produced based on the comparison. The searchable image characteristics and text terms may be indexed in a uniform data format that enables a search engine to use the same search methodology to search for both images and text. The uniform data format may be an inverted index data format. The produced search result may include identifiers for one or more images and text segments that have been retrieved for display in a ranked manner based on similarity metrics.
