Abstract

Personalized searching for information in a distributed data processing system including providing in a search portal a personal search term list for a user, the personal search term list comprising search keywords known to be of interest to the user; receiving from the user a navigation identification message comprising a navigation location; and creating a personalized search index in dependence upon the navigation location and the contents of the personal search term list, wherein the personalized search index comprises index records comprising time stamps. Typical embodiments also comprise receiving in the search portal from the user a navigation request message comprising a navigation direction; creating, in dependence upon the personalized search index, the navigation direction, and a last navigation time stamp, a response to the navigation request message; transmitting the response to the user; and updating the last navigation time stamp.

7. The method of claim 1 further comprising:

receiving in the search portal from the user a navigation request message comprising a navigation direction;

creating, in dependence upon the personalized search index, the navigation direction, and a last navigation time stamp, a response to the navigation request message;

transmitting the response to the user; and

updating the last navigation time stamp.

8. The method of claim 7 wherein creating a response comprises:

retrieving, from user account data, a last navigation time stamp;

retrieving a navigation location from the personalized search index in dependence upon the last navigation time stamp from the user account data and the navigation direction; and

retrieving the document identified by the navigation location;

wherein transmitting the response to the user comprises transmitting the document to the user.

9. The method of claim 8 wherein the navigation request message further comprises a navigation interval and retrieving a navigation location from the personalized search index further comprises retrieving a navigation location from the personalized search index in dependence upon the last navigation time stamp from the user account data, the navigation direction, and the navigation interval.

10. The method of claim 1 further comprising:

creating a subset of the personalized search index; and

making the subset available to users for remote playback.

11. A system for personalized searching for information in a distributed data processing system, the system comprising:

means for providing in a search portal a personal search term list for a user, the personal search term list comprising search keywords known to be of interest to the user;

means for receiving from the user a navigation identification message comprising a navigation location; and

means for creating a personalized search index in dependence upon the navigation location and the contents of the personal search term list, wherein the personalized search index comprises index records, each index record comprising a time stamp.

12. The system of claim 11 wherein the time stamp comprises an indication of the date and time of a receiving of the navigation identification message.

13. The system of claim 11 wherein the personalized search index comprises a search index further comprising a user identification for the search portal, the user identification for the search portal comprising data uniquely identifying the user as among other users of the search portal.

14. The system of claim 11 wherein the navigation identification message further comprises a search keyword and means for creating a personalized search index further comprises means for indexing the search keyword with the navigation location and a time stamp in the personalized search index.

15. The system of claim 11 wherein means for creating a personalized search index further comprises:

means for retrieving a document from the navigation location;

means for identifying search keywords from the personal search term list that occur in the retrieved document; and

means for indexing in the personalized search index the navigation location, a time stamp, and keywords from the personal search term list that occur in the retrieved documents.

16. The system of claim 11 further comprising means for establishing a user account for the user on the search portal, the user account comprising user identification unique to the user and a last navigation time stamp.

17. The system of claim 11 further comprising:

means for receiving in the search portal from the user a navigation request message comprising a navigation direction;

means for creating, in dependence upon the personalized search index, the navigation direction, and a last navigation time stamp, a response to the navigation request message;

means for transmitting the response to the user; and

means for updating the last navigation time stamp.

18. The system of claim 17 wherein means for creating a response comprises:
