This specification describes systems and methods for a domain-based search engine. One aspect of the invention provides a computer implemented method including: receiving a query that identifies an entity; identifying a domain that has the entity as a member; obtaining an entity-to-domain weight; identifying a precedent set connected to the domain; obtaining a precedent-set-to-domain weight; identifying an event in the precedent set; determining a score for the event based at least in part on (i) the entity to domain weight and (ii) the precedent set to domain weight; and providing rendering data for the event when the score satisfies a specified threshold. The rendering data can include a selectable link and the method can further include receiving a selection of the selectable link and in response to receiving the selection, providing rendering data that is indicative of an impact of the event on an entity.
