**Globus definition:** The [Globus Search](https://www.globus.org/platform/services/search) is a set of capabilities that can be incorporated into data management applications, either in conjunction with, or independently of, other Globus features such as file transfer and data sharing. The starting point is to provide Globus Search with metadata. Unlike many other services, there is no prescribed “metadata schema”; Globus Search will ingest metadata of arbitrary structure and make it available for faceted search. The primary element of the service is the index, which is the vehicle for storing metadata, setting permissions, and performing searches.
