1. An example management system, comprising: at least one computer; an indexing engine executable by the at least one computer to index content of source business oriented metadata, the source business oriented metadata including an authored topic hierarchy, the indexing engine having a content scanner that reads the source business oriented metadata included in source metadata documents containing terms to be indexed, and builds a content index of the source business oriented metadata, wherein the content scanner builds, as the content index, one or more knowledge base documents, wherein, for each term in the source metadata documents, the content scanner stores, in the one or more knowledge base documents, a knowledge base representation of the term along with one or more references to content of the source business oriented metadata that uses the term, and wherein the one or more knowledge base documents include a representation of a structure of the authored topic hierarchy; an index store that stores the content index of the source business oriented metadata; and an example engine executable by the at least one computer to use the representation of the structure of the authored topic hierarchy to determine logical associations among the terms in the source metadata documents, store the logical associations in the one or more knowledge base documents, and manage logical associations of terms in a query using the one or more knowledge base documents of the content index, wherein the example engine determines an example association between two terms when a term is an example of another term, and wherein the example engine combines terms into phrases and determines, based on example associations between terms in the phrases, an example association between two phrases when a phrase is an example of another phrase.
