Abstract

Methods and apparatus, including computer program products, for performing text and attribute searches of data stores that include business objects. A computer-implemented method for searching business objects includes receiving search criteria, providing the search criteria to one or more search engines, receiving search results from the search engines, defining a result list from the search results, and providing the result list. At least one of the search engines accesses an index of business objects.

Claims

1. A computer implemented method for searching business objects, the method comprising:

processing the business objects, wherein processing comprises obtaining attributes of the business objects and unrolling a structure of the attributes to produce linear text;

receiving search criteria;

providing the search criteria to one or more search engines, at least one of the search engines accessing the business objects;

receiving search results from the search engines;

defining a result list from the search results; and

providing the result list.

2. The method of claim 1, wherein:

receiving search criteria includes receiving a text string; and

providing the search criteria to one or more search engines includes providing the search criteria to a search engine that performs a full text search.

3. The method of claim 2, wherein:

providing the search criteria to one or more search engines includes providing the search criteria to heterogeneous search engines.

4. The method of claim 2, wherein:

providing the search criteria to one or more search engines includes providing the search criteria to a first search engine that accesses a first index of a first type of data object and, furthermore, to a second search engine that accesses a second index of any combination of a second type of data object and the first type of data object.

5. The method of claim 4, wherein:

sending the search criteria to one or more search engines includes sending the search criteria to a search engine that accesses an index of Web pages.

6. The method of claim 1, further comprising:

identifying, from the received search results, results that are not authorized to be provided; and

excluding from the result list the search results identified as not authorized to be provided.

7. The method of claim 6, wherein:

receiving search criteria includes receiving search criteria from a user, the user having an authorized access level; and

excluding results from the result list includes determining, based on the user'"'"'s authorization access level, whether the user is authorized to access data objects represented by the results.

8. The method of claim 1, further comprising:

receiving a user selection of an element of the result list; and

providing read access to the element.

9. The method of claim 8, further comprising:

receiving a request to edit the element; and

providing write access to the element.

10. The method of claim 8, further comprising:

receiving a request to add the element to a favorite list; and

adding the element to the favorite list.

11. The method of claim 1, further comprising:

providing a unified user interface to search in accordance with the search criteria, the unified user interface interacting with the one or more search engines.

12. The method of claim 11, wherein:

providing a user interface includes including the user interface in a portal.

13. The method of claim 12, wherein:

providing a user interface includes providing an adaptive user interface that presents different attributes for different types of business objects.

14. A computer program product, tangibly stored on one or more machine readable media, for searching data stores that include business objects, the product comprising instructions operable to cause a processor to:

process the business objects, wherein processing comprises obtaining attributes of the business objects and unrolling a structure of the attributes to produce linear text;

receive search criteria;

send the search criteria to one or more search engines, at least one of the search engines accessing the business objects;

receive search results from the search engines;

define a result list; and

provide the result list.

15. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

receive a restriction specifying a format-dependent condition of a business object as the search criteria.

16. The computer program product of claim 15, wherein the instructions are operable to cause the processor to:

receive the restriction specifying that the business object be of a particular class of business object.

17. The computer program product of claim 15, wherein the instructions are operable to cause the processor to:

receive the restriction specifying that an attribute of the business object have a particular value.

18. The computer program product of claim 15, wherein the instructions are operable to cause the processor to:

send the restriction to the at least one search engine that accesses the index of business objects.

19. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

order the received search results in the result list according to relevance.

20. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

assess the relevance of the received search results.

21. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

receive a text string in the search criteria; and

provide the search criteria to a search engine that performs a full text search.

22. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

provide the search criteria to heterogeneous search engines.

23. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

provide the search criteria to a first search engine that accesses a first index of a first type of data object and to a second search engine that accesses a second index of any combination of a second type of data object and the same type of data object.

24. The computer program product of claim 23, wherein the instructions are operable to cause the processor to:

send the search criteria to a search engine that accesses an index of Web pages.

25. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

identify, from the received search results, results that are not authorized to be provided; and

exclude from the result list the search results identified as not authorized to be provided.

26. The computer program product of claim 25, wherein the instructions are operable to cause the processor to:

receive search criteria from a user, the user having an authorized access level; and

exclude results from the result list by determining, based on the user'"'"'s authorization access level, whether the user is authorized to access data objects represented by the results.

27. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

receive a user selection of an element of the result list; and

provide read access to the element.

28. The computer program product of claim 27, wherein the instructions are operable to cause the processor to:

receive a request to edit the element; and

provide write access to the element.

29. The computer program product of claim 27, wherein the instructions are operable to cause the processor to:

receive a request to add the element to a favorite list; and

add the element to the favorite list.

30. The computer program product of claim 14, wherein the instructions are operable to cause the processor to:

provide a unified user interface to search in accordance with the search criteria, the unified user interface interacting with the one or more search engines.

31. The computer program product of claim 30, wherein the instructions are operable to cause the processor to:

include the user interface in a portal.

32. The computer program product of claim 31, wherein the instructions are operable to cause the processor to:

provide an adaptive user interface that presents different attributes for different types of business objects.
