11. A method for dynamically reclassifying and retrieving at least a target information object among a plurality of information objects stored on a memory, a plurality of attribute classifiers corresponding to the information objects, wherein each of the information objects has at least one of the attribute classifiers, comprising: receiving a determined first attribute classifier; after receiving the determined first attribute classifier, a central processing unit determines a plurality of first information objects, wherein each of the first information objects has the determined first attribute classifier, and the central processing unit removes the attribute classifiers which do not correspond to any of the first information objects; in wherein the attribute classifiers not removed by the central processing unit comprise remained attribute classifiers each corresponding to at least one of the first information objects; visibly displaying the remained attribute classifiers, and the remained attribute classifiers are a part of a search result; when at least two of the remained attribute classifiers correspond to a same subset of the first information objects, combining the at least two of the remained attribute classifiers in a combined form to serve as a hint, wherein the combined form of the remained attribute classifiers are simply listed, grouped, circled, or marked; and displaying the hint.

The method according to claim 11 , wherein after receiving the determined first attribute classifier, according to at least a user input signal, the central processing unit determines at least a second attribute classifier among the remained attribute classifiers, the determined at least one second attribute classifier is combinable with at least one of the remained attribute classifiers visibly, when the first information objects which the second attribute classifier corresponds to are included in the first information objects which the combined one of the remained attribute classifiers corresponds to.
