Search system using search subdomain and hints to subdomains in search query statements and sponsored results on a subdomain-by-subdomain basis

1. A method comprising:

identifying an ambiguous term in a search query string;

determining a disambiguated term associated with the ambiguous term based, at least in part, on a location associated with a search request for the search query string;

substituting the disambiguated term for the ambiguous term in the search query string to produce a modified search query string included in a modified search request;

directing the modified search request to a search server;

wherein the method is performed by one or more computing devices.

2. One or more non-transitory computer-readable storage media storing instructions which, when executed by one or more processors, cause performance of:

identifying an ambiguous term in a search query string;

determining a disambiguated term associated with the ambiguous term based, at least in part, on a location associated with a search request for the search query string;

substituting the disambiguated term for the ambiguous term in the search query string to produce a modified search query string included in a modified search request;

directing the modified search request to a search server.

3. The method of claim 1 , wherein the ambiguous term in the search engine query is adjacent to a disambiguation hint.

4. The method of claim 1 , wherein the location associated with the search request is stored as a preference of the user.

5. The method of claim 1 , wherein the location associated with the search request is associated with a dialect.

6. The method of claim 5 , wherein disambiguated term is determined based on the dialect.

7. The method of claim 1 , further comprising:

directing the search query string to the search server;

receiving search results comprising results found based on the search query string and results found based on the modified search request.

8. The method of claim 1 , further comprising determining the location based on an IP address associated with the search query string.

9. The method of claim 1 , further comprising determining the location based on a mobile access point associated with the search query string.

10. The method of claim 1 , wherein disambiguated term is determined based on a history of search results selected by the user.

11. The method of claim 1 , wherein disambiguated term is determined based on detecting implicitly local searches.

12. The computer-readable storage media of claim 2 , wherein the ambiguous term in the search engine query is adjacent to a disambiguation hint.

13. The computer-readable storage media of claim 2 , wherein the location associated with the search request is stored as a preference of the user.

14. The computer-readable storage media of claim 2 , wherein the location associated with the search request is associated with a dialect.

15. The method of claim 14 , wherein disambiguated term is determined based on the dialect.

16. The computer-readable storage media of claim 2 , wherein the instructions cause performance of:

directing the search query string to the search server;

receiving search results comprising results found based on the search query string and results found based on the modified search request.

17. The computer-readable storage media of claim 2 , wherein the instructions cause performance of:

determining the location based on an IP address associated with the search query string.

18. The computer-readable storage media of claim 2 , wherein the instructions cause performance of:

determining the location based on a mobile access point associated with the search query string.

19. The computer-readable storage media of claim 2 , wherein disambiguated term is determined based on a history of search results selected by the user.

20. The computer-readable storage media of claim 2 , wherein disambiguated term is determined based on detecting implicitly local searches.
