Existing search engine, the search input box can only be entered in character as the carrier of information.
Perfect search engine, the search input box should be able to enter information expressed in a variety of carriers. For example: a picture, you can picture the name, classification, content and other information, enter the characters in the search input box to query the information. However, too much trouble, if the input box to paste the image, import, treat the character as much for convenience. Moreover, if the picture is the name of the meaningless, nothing to do with the picture; its classification and content can be expressed but not too clear, then the query for this picture unlikely. Another example: a sound file, a video file and so on.
It is unclear which is more convenient, more powerful search engine in it. |
