1. A method to enrich search results with metadata, the method comprising:
receiving a plurality of metadata based on a lineage relationship and an impact relationship associated with an entity; storing the plurality of metadata in a repository; receiving a search request associated with the entity; and determining search results that comprise a portion of the plurality of metadata stored in the repository, where the portion of the plurality of metadata that is transmitted is based on a score calculation associated with score(q,d)=∑t⁢⁢i⁢⁢n⁢⁢q⁢⁢(tf⁡(t⁢⁢in⁢⁢d)1/2·idf⁡(t)2·*(∑p⁢⁢i⁢⁢n⁢⁢parents⁢⁢relationshipf⁡(t,d)*depth⁡(nth)*score⁡(p)))wherein t is a term, q is a query, tf is a frequency of the term t, d is a document, depth (nth) is a level of depth of an object to a top object, p is a parent, relationshipf(t,d ) is a relationship of the document, and idf is an inverse document frequency of the term.
