1. A system for dynamically reclassifying and retrieving at least a target information object among a plurality of information objects, comprising: a memory, storing the information objects and a plurality of attribute classifiers corresponding to the information objects; and a central processing unit in signal connection with the memory, after determination of a first attribute classifier, the central processing unit determining a plurality of first information objects corresponding to the determined first attribute classifier and a plurality of remained attribute classifiers each corresponding to at least one of the first information objects; wherein the remained attribute classifiers are visibly displayable through the system as at least a part of a search result, and upon a temporary user selection on at least one of the remained attribute classifiers, at least two of the remained attribute classifiers are combinable as a displayable dynamical reclassifying hint when corresponding to at least the same one of the first information objects.
