Embodiments of the invention provide a system and method for searching and reporting on semistructured data that can include dynamic metadata. One embodiment can comprise providing a user interface to a user based on an object type definition for an object type that allows the user to specify search criteria associated with a set of metadata, mapping the user search criteria to a query that comprises at least one structured query constraint and at least one unstructured query constraint, processing the query to search a set of data objects containing semistructured data associated with the object type according to the query and returning a set of results to the user. The search results can be returned to a user based on user-specified reporting parameters. Additionally, the reporting definition can be saved as an object for future execution.
