Abstract

A method and system for updating searches on an online auction site are described. In one embodiment, a database of auction postings is automatically searched based upon at least one search criteria to produce at least one new search result. The at least one new search result is compared with at least one previous search result. In addition, an e-mail notification of the result of the comparison is sent to a user notifying a user of the comparison.

Claims

1. A computer-implemented method, comprising:

searching a plurality of data items to produce a current search result, the current search result identifying one or more data items that satisfy at least one user-specific search criteria;

extracting, using one or more processors, a previous search result of a previous search from memory, the previous search performed based upon same search criteria as the at least one user-specific search criteria; and

comparing the current search result using the user-specified search criteria with the previous search result, the comparing to automatically detect from the current search result at least one data item that is new or modified as compared to the previous search result.

2. The computer-implemented method of claim 1, further comprising sending notification of a result of the comparing to a user device.

3. The computer-implemented method of claim 2, wherein the notification of the result of the comparing is selected from the group including an e-mail notification, a web page notification, a facsimile notification, and a pager notification.

4. The computer-implemented method of claim 1, wherein at least one of the extracting and the comparing is performed on a periodic basis.

5. The computer-implemented method of claim 1, wherein the comparing comprises:

parsing the current search result; and

performing a checksum on the current search result that is parsed.

6. The computer-implemented method of claim 5, wherein the parsing comprises:

dividing the current search result into one or more sections, each section representing a corresponding data item within a database of data items; and

tagging each section of the one or more sections.

7. The computer-implemented method of claim 1, wherein the at least one data item is linked to a web page.

8. The computer-implemented method of claim 7, further comprising displaying contents of the web page via a user device.

9. The computer-implemented method of claim 7, wherein the web page comprises information associated with a non-sale item.

21. The computer-implemented method of claim 1, wherein the at least one data item satisfies the at least one user-specific search criteria.

22. The computer-implemented method of claim 1, wherein the at least one data item comprises an item listing associated with an item for transaction.

10. A system comprising:

a searching engine to search a plurality of data items to produce a current search result, the current search result identifying one or more data items that satisfy at least one user-specific search criteria;

an extracting engine to extract, using one or more processors, a previous search result of a previous search from memory, the previous search performed based upon same search criteria as the at least one user-specific search criteria; and

a comparing engine to compare the current search result using the user-specified search criteria with the previous search result to automatically detect from the current search result at least one data item that is new or modified as compared to the previous search result.

11. The system of claim 10, further comprising a sending engine to send notification of a result of the comparing to a user device.

12. The system of claim 11, wherein the notification of the result of the comparing is selected from the group including an e-mail notification, a web page notification, a facsimile notification, and a pager notification.

13. The system of claim 10, wherein at least one of the extracting and the comparing is performed on a periodic basis.

14. The system of claim 10, wherein the comparing engine is to:

parse the current search result; and

perform a checksum on the current search result that is parsed.

15. The system of claim 14, wherein the comparing engine is further to:

divide the current search result into one or more sections to parse the current search result, each section representing a corresponding data item within a database of data items; and

tag each section of the one or more sections.

16. The system of claim 10, wherein the at least one data item is linked to a web page.

17. The system of claim 16, further comprising a displaying engine to display contents of the web page via a user device.

18. The system of claim 16, wherein the web page comprises information associated with a non-sale item.

19. A non-transitory computer-readable medium storing instructions, which when executed by a processor, cause the processor to perform operations comprising:

searching a plurality of data items to produce a current search result, the current search result identifying one or more data items that satisfy at least one user-specific search criteria,

extracting a previous search result of a previous search from memory, the previous search performed based upon same search criteria as the at least one user-specific search criteria; and

comparing the current search result using the user-specified search criteria with the previous search result, the comparing to automatically detect from the current search result at least one data item that is new or modified as compared to the previous search result.

20. The computer-readable medium of claim 19, further comprising instructions, which when executed by the processor, cause the processor to send notification of a result of the comparing to a user device.
