Customized, personalized, integrated client-side search indexing of the web

1. A method, in a client data processing system, for personalized, integrated search indexing, the method comprising:

loading a set of configuration options at the client data processing system, wherein the configuration options define user preferences for client-side indexing;

identifying, at the client data processing system, a portion of Web content to index based on the set of configuration options;

indexing, at the client data processing system, the portion of Web content at a client-side indexer based on the set of configuration options to form a client-side search index, wherein the client-side search index is personalized for a user associated with the client-side indexer;

sending a search query from the client data processing system to a Web search engine server data processing system with the client-side search index attached to the search query; and

performing a search based on the search query using a combination of the client-side search index and a server-side search index associated with the Web search engine data processing system, wherein the Web search engine data processing system combines the client-side search index with the server-side search index to form a combined search index and performs a search to satisfy the search query using the combined search index responsive to the client-side search index being more up-to-date than the server-side search index, wherein the portion of Web content is a subset of Web content indexed in the server-side search index.

9. The method of claim 1 , wherein the client-side search index has a first timestamp and the server-side search index has a second timestamp, the method further comprising:

comparing the first timestamp of the client-side search index with the second timestamp of the server-side search index to determine whether the client-side search index is more up-to-date than the server-side search index.

10. The method of claim 1 , wherein the client-side indexer automatically indexes the portion of Web content when the client data processing system is idle.

11. A computer program product comprising a computer readable storage medium having a computer readable program recorded thereon, wherein the computer readable program, when executed on a client data processing system, causes the client data processing system to:

load a set of configuration options at the client data processing system, wherein the configuration options define user preferences for client-side indexing;

identify, at the client data processing system, a portion of Web content to index based on the set of configuration options;

index, at the client data processing system, the portion of Web content at a client-side indexer based on the set of configuration options to form a client-side search index, wherein the client-side search index is personalized for a user associated with the client-side indexer;

send a search query from the client data processing system to a Web search engine server data processing system with the client-side search index attached to the search query; and

perform a search based on the search query using a combination of the client-side search index and a server-side search index associated with the Web search engine data processing system, wherein the Web search engine data processing system combines the client-side search index with the server-side search index to form a combined search index and performs a search to satisfy the search query using the combined search index responsive to the client-side search index being more up-to-date than the server-side search index, wherein the portion of Web content is a subset of Web content indexed in the server-side search index.

12. The computer program product of claim 11 , wherein identifying a portion of Web content to index comprises identifying a set of previous search results, identifying a set of most visited Web sites, identifying a set of bookmarks or favorites, identifying flagged sites, or identifying a set of sites visited by users with similar interests.

13. The computer program product of claim 11 , wherein indexing the portion of Web content comprises:

receiving a client-side index from a peer data processing system; and

combining the client-side index from the peer data processing system with the client-side search index.

14. The computer program product of claim 11 , wherein the set of configuration options includes a first indexing algorithm and wherein the client-side indexer indexes a first portion of Web content using the first indexing algorithm, and wherein the set of configuration options includes a second indexing algorithm and wherein the client-side indexer indexes a second portion of Web content using the second indexing algorithm.

15. The computer program product of claim 11 , wherein the client-side search index has a first timestamp and the server-side search index has a second timestamp, wherein the computer readable program further causes the client data processing system to:

compare the first timestamp of the client-side search index with the second timestamp of the server-side search index to determine whether the client-side search index is more up-to-date than the server-side search index.

16. A client data processing system, comprising:

a processor; and

a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:

load a set of configuration options at the client data processing system, wherein the configuration options define user preferences for client-side indexing;

identify, at the client data processing system, a portion of Web content to index based on the set of configuration options;

index, at the client data processing system, the portion of Web content at a client-side indexer based on the set of configuration options to form a client-side search index, wherein the client-side search index is personalized for a user associated with the client-side indexer;

send a search query from the client data processing system to a Web search engine server data processing system with the client-side search index attached to the search query; and

perform a search based on the search query using a combination of the client-side search index and a server-side search index associated with the Web search engine data processing system, wherein the Web search engine data processing system combines the client-side search index with the server-side search index to form a combined search index and performs a search to satisfy the search query using the combined search index responsive to the client-side search index being more up-to-date than the server-side search index, wherein the portion of Web content is a subset of Web content indexed in the server-side search index.

17.
