Embodiments of the present invention provide techniques for searching enterprise data using semantic information associated with enterprise applications. One or more searchable data definitions that describe searchable data associated with one or more enterprise applications may identify semantic relationships among searchable data in the application. An ontology for the application that describes semantic relationships among data associated with the application may be generated from the searchable data definitions. The ontology may be used to execute search queries and provide search results that include or result from semantic relationships among the searched data.
