Abstract: A system and a method of performing a category search for a plurality of structured documents which are stored in a database are provided. According to the method, one or more categorization fields of the structured documents and a search query are initially input by a user. A search engine then searches the structured documents according to the search query to obtain a plurality of searched documents. Further, contents of the categorization fields of the searched documents are retrieved by a feeder. The searched documents are then categorized by a categorization engine to obtain categorization results solely based on the contents of the categorization fields of the searched documents.
