  • METHOD AND APPARATUS FOR TEXT SEARCHING ON A TOUCH TERMINAL
    Publication number: 20140109009
    Abstract: Various embodiments provide methods and apparatus for text searching on a touch terminal. In an exemplary method, the touch terminal can obtain a touch selection command. The touch terminal can interpret the touch selection command and determine text information corresponding to the touch selection command. The touch terminal can send the text information to a backstage server, and then receive and display search results returned from the backstage server and corresponding to the text information. Search results can thus be obtained by directly selecting text content on the touch terminal to trigger the backstage server to conduct a searching operation of the selected text content.
