Abstract: Embodiments include a computer-implemented method that includes identifying a candidate parent entity having one or more characteristics indicative of the entity having a parent hierarchical relationship to another entity of an entity set, identifying a candidate child entity set including entities of the entity set that each have one or more characteristics indicative of the entity having a child hierarchical relationship to the candidate parent entity, comparing characteristics of the candidate parent entity to characteristics of an entity of the candidate child entity set to determine whether a hierarchical relationship exists between the candidate parent entity and the entity of the candidate child entity set, determining that a hierarchical relationship exists between the candidate parent entity and the entity of the candidate child entity set, and updating a hierarchical index to reflect the hierarchical relationship between the candidate parent entity and the entity of the candidate child entity set.

Abstract: Embodiments include a computer-implemented method that includes receiving a search query, processing the search query to identify a set of search results, determining that the set of search results includes a parent search result corresponding to a parent entity, in response to determining that the set of search results includes a parent search result, identifying a set of child search results including one or more child search results that correspond to entities that are children of the parent entity, and providing a hierarchical search results list for display. The hierarchical search results list including a first listing of search results corresponding to the set of search results, and a second listing of search results corresponding to the set of child search results. The second listing to be displayed in hierarchical relation to a search result corresponding to the parent search result.
