1. A method of searching for data in heterogeneous data sources with a computer system, the method comprising:
- receiving a request for data at a given federated data source; and
from the given federated data source, retrieving data from a plurality of datastores, including;
data from one or more terminal data repositories,data, with a schema conceptual view of the data, from one or more other federated data sources, wherein the one or more other federated data sources are recursively arranged, anddata, without a schema conceptual view of the data, from one or more search gateway data sources, said search gateway data sources expanding the received request into other data sources, wherein said other data sources include at least a file system and a relational database;
the given federated data source providing a unified schema conceptual view of;
(a) the data from the plurality of datastores, (b) the data from the terminal data repositories, (c) the data and schema conceptual view from the other federated data sources, and (d) the data from one or more search gateway data sources.

Abstract
An architecture to enable search gateways as part of a federated search supports searching for data in one or more heterogeneous data sources. The one or more heterogeneous data sources are within a computer system. Initially, a request for data is received at a federated data source. From the federated data source, data is retrieved from one or more of one or more terminal data repositories or one or more search gateway data sources.

9. An apparatus for searching for data in one or more heterogeneous data sources, comprising:
-
a computer system accessing said one or more heterogeneous data sources; and one or more computer programs, performed by the computer system, for; receiving a request for data at a given federated data source; and from the given federated data source, retrieving data from a plurality of datastores, including; data from one or more terminal data repositories, data, with a schema conceptual view of the data, from one or more other federated data sources, wherein the one or more other federated data sources are recursively arranged, and data, without a schema conceptual view of the data, from one or more search gateway data sources, said search gateway data sources expanding the received request into other data sources, wherein said other data sources include at least a file system and a relational database; the given federated data source providing a unified schema conceptual view of;
(a) the data from the plurality of datastores, (b) the data from the terminal data repositories, (c) the data and schema conceptual view from the other federated data sources, and (d) the data from one or more search gateway data sources. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An article of manufacture comprising a program storage medium readable by a computer and embodying one or more instructions executable by the computer to perform method steps for searching for data in one or more heterogeneous data sources within a computer system, the method comprising:
-
receiving a request for data at a given federated data source; and from the given federated data source, retrieving data from a plurality of datastores, including; data from one or more terminal data repositories, data, with a schema conceptual view of the data, from one or more other federated data sources, wherein the one or more other federated data sources are recursively arranged, and data, without a schema conceptual view of the data, from one or more search gateway data sources, said search gateway data sources expanding the received request into other data sources, wherein said other data sources include at least a file system and a relational database; the given federated data source providing a unified schema conceptual view of;
(a) the data from the plurality of datastores, (b) the data from the terminal data repositories, (c) the data and schema conceptual view from the other federated data sources, and (d) the data from one or more search gateway data sources. - View Dependent Claims (17, 18, 19, 20, 21, 22)
