1. A system for metadata searching, the system comprising: a memory; a processor; a receiving module configured for 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; a query module configured for 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; and 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 an output module configured for 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 system of claim 1 , wherein a type of the search query is at least one of: a first query type designating a group of keywords to obtain metadata resources comprising text segments including the designated group of keywords; a second query type designating a group of keywords to obtain metadata resources that have relationship paths to metadata resources comprising text segments including the designated group of keywords; a third query type designating a group of keywords and a type of metadata resources, to obtain metadata resources comprising text segments including the designated group of keywords and that are of the designated; a fourth query type designating a group of keywords and a type of metadata resources to obtain metadata resources comprising the designated type and having relationship paths to metadata resources comprising text segments including the designated group of keywords; and a fifth query type designating a first group of keywords, a second group of keywords, and a relationship to obtain a first set of metadata resources, the first set of metadata resources having relationship paths to a second metadata resources and the relationship paths comprising the designated relationship, wherein the first set of metadata resources comprises at least one of the first group of keywords and relationship paths to metadata resources comprising the first group of keywords, and wherein the second set of metadata resources comprises at least one of the second group of keywords and relationship paths to metadata resources comprising the second group of keywords.
