Abstract

A method includes querying a plurality of search engines for properties to identify for which content categories the search engines are suited. A query to locate content is communicated to those of the plurality of search engines suited to service the query to locate content, based on at least one content category of the query to locate content.

Claims

1. A method for identifying for which content categories a selected one of a plurality of search engines is suited, comprising:

receiving a query for properties to identify the content categories for which the selected search engine is suited; and

receiving a query to locate content based on at least one content category of the identified content categories.

2. The method of claim 1, further comprising returning engine properties by the selected search engine in response to the query for properties to identify for which content categories the selected search engine is suited.

3. The method of claim 2, further comprising:

communicating, by the selected search engine, with others of the plurality of search engines the query for properties to identify for which content categories the other engines are suited; and

combining the engine properties, by the selected search engine, with properties returned from the others of the plurality of search engines in response to the query for properties from the selected engine; and

returning the combined properties in response to the query for properties to identify for which content categories the selected search engine is suited.

4. The method of claim 1, further comprising returning search results in response to the query to locate content based on at least one content category of the identified content categories for which the selected search engine is suited.

5. The method of claim 4, further comprising:

communicating, by the selected search engine, with others of the plurality of search engines, the query to locate content based on at least one of content categories for which the others of the plurality of search engines are suited;

combining the search results, by the selected search engine, with results returned from the others of the plurality of search engines in response of the query from the selected engine to locate content; and

returning the combined results, by the selected search engine, in response to the query to locate content based on at least one content category of the identified content categories.

6. The method of claim 5, further comprising identifying a search result by a search engine that obtains the search result.

7. The method of claim 1, wherein receiving by the selected one of the plurality of search engines to locate content comprises receiving the query via a CGI entry point.

8. The method of claim 1, wherein the query to locate content comprises at least a subset of an Internet URL syntax.

9. The method of claim 1, wherein the query to locate content comprises at least a subset of an SQL syntax.

10. The method of claims 4, wherein the returned search results comprise an XML format.

11. An article comprising:

a machine accessible medium having associated content for identifying for which content categories a selected one of a plurality of search engines is suited, wherein when the content is accessed, the content provides for;

receiving a query for properties to identify the content categories for which the selected search engine is suited; and

receiving a query to locate content based on at least one content category of the identified content categories.

12. The article of claim 11, further comprising content, which when accessed, provides for returning engine properties by the selected search engine in response to the query for properties to identify for which content categories the selected search engine is suited.

13. The article of claim 12, further comprising content, which when accessed, provides for:

communicating, by the selected search engine, with others of the plurality of search engines the query for properties to identify for which content categories the other engines are suited; and

combining the engine properties, by the selected search engine, with properties returned from the others of the plurality of search engines in response to the query for properties from the selected engine; and

returning the combined properties in response to the query for properties to identify for which content categories the selected search engine is suited.

14. The article of claim 11, further comprising content, which when accessed, provides for returning search results in response to the query to locate content based on at least one content category of the identified content categories for which the selected search engine is suited.

15. The article of claim 14, further comprising content, which when accessed, provides for:

communicating, by the selected search engine, with others of the plurality of search engines, the query to locate content based on at least one of content categories for which the others of the plurality of search engines are suited;

combining the search results, by the selected search engine, with results returned from the others of the plurality of search engines in response of the query from the selected engine to locate content; and

returning the combined results, by the selected search engine, in response to the query to locate content based on at least one content category of the identified content categories.

16. The article of claim 15, further comprising content, which when accessed, provides for identifying a search result by a search engine that obtains the search result.

17. The article of claim 11, wherein content for providing for receiving by the selected one of the plurality of search engines to locate content comprises content, which when accessed, provides for receiving the query via a OGI entry point.

18. The article of claim 11, wherein the query to locate content comprises at least a subset of an Internet URL syntax.

19. The article of claim 11, wherein the query to locate content comprises at least a subset of an SQL syntax.

20. The article of claim 14, wherein the returned search results comprise an XML format.

21. A search system, comprising:

a client to form a query and to communicate the query to a server to locate desired content;

a server to receive the query, to process the query, to query selected ones of a plurality of search engines to identify content categories for which the selected search engines are suited, and to return search results to the client; and

at least one search engine to locate content based on the query processed by the server and to return the located content back to the server.

22. The search system of claim 21, wherein the client comprises:

a device comprising a processor and memory to store instructions and data for execution; and

a web browser running by the device to facilitate communications between the client and the server.

23. The search system of claim 21, wherein the server comprises a search manager to ascertain content categories for the query, to facilitate identifying a suitable search engine to service the query having the ascertained content categories, to send the query to the suitable search engine to locate content, and to receive search results from the suitable search engine.

24. A search system, comprising:

a client to form a query and to communicate the query to a server to locate desired content;

a server to receive the query, to ascertain content categories for the query, and to return search results to the client;
