10. A method implemented on an electronic data processing system for performing a metadata resources search, the method comprising: receiving a search query with respect to a plurality of metadata resources, wherein each of the plurality of metadata resources comprises data describing a set of other data, and wherein each of the plurality of metadata resources comprises structural information comprising at least relationship path information between the metadata resource and at least one other of the plurality of metadata resources, wherein the search query comprises at least one keyword associated with textual information in each of the plurality of metadata resources without designating all structural information among the plurality of metadata resources; parsing the search query; identifying a set of related metadata resources within the plurality of metadata resources based on at least the relationship path information within the structural information of each of the plurality of metadata resources; searching, based on the parsing, each of the set of related metadata resources based on the textual information and the structural information of each of the set of related metadata resources; forming, based on the searching, a set of search results comprising, the search results comprising at least one of the set of related metadata resources comprising textual information satisfying the at least one keyword, and complete structural information between the at least one of the set of related metadata resources and at least one other of the set of related metadata resources; and outputting the search results so as to realize a fuzzy structural search with respect to the plurality of metadata resources, the fuzzy structural search utilizing the search query, which is absent at least a designation of the relationship path information among the plurality of metadata resources, to obtain the set of search results, which comprises the complete structural information between the at least one of the set of related metadata resources and at least one of the set of related metadata resources.

The method of claim 10 , wherein the outputting comprises: sorting the at least one of the set of related metadata resources and the at least one other of the set of related metadata, the sorting being performed according to a measurement based on keyword matching and a measurement based on a set of relationship paths between the at least one of the set of related metadata resources and the at least one other of the set of related metadata resources.
