Image search options Leave feedback
This page contains a description of all search options that can be specified in an instance of the ImageSearchOptions class.
The HashDifferences property allows you to specify the maximum number of mismatched bits in the image hash. If all the bits in the hash match, then the images match completely. The more different bits, the more the images differ from each other. The default value of the property is 5. Since the image hash is 64 bits long, the meaningful values are in the range from 0 to 64: a value greater than 64 is treated as 64, and a negative value means that no images are found.
The MaxResultCount property allows you to specify the maximum number of found images for a reverse image search request. The found images with fewer mismatched bits are returned first. The default value is 1000.
The SearchDocumentFilter property allows you to specify the filter of documents returned as a search result. By default, all documents found will be returned as a search result. For details, see the Document filtering in search result page.
