Abstract

An approach is provided for utilizing a scalable data structure. A query specifying an entity identifier and requested content is received. A search is caused, at least in part, the search based on the entity identifier of a profile index of data structures, each specifying a profile field that is associated with an access control field to yield a search result. Access rights to the requested content are indicated for the entity identifier. The data structures further include the profile field and the access control field.

Claims

1. A method comprising:

receiving a query specifying an entity identifier and requested content;

causing, at least in part, a search based on the entity identifier of a profile index of data structures, each specifying a profile field that is associated with an access control field to yield a search result; and

indicating access rights to the requested content for the entity identifier,

wherein the data structures further include the profile field and the access control field.

2. A method of claim 1, further comprising:

retrieving the requested content based on the access rights, wherein the search yields only the search results that are indicated to have access.

3. A method of claim 1, wherein the profile index is searched based on a comparison of the entity identifier and the access control field.

4. A method of claim 1, wherein the access control field includes a plurality of entity identifiers.

5. A method of claim 4, wherein the profile field is a basic profile field and the data structure further includes an extended profile field, and wherein the access control field is utilized to specify access rights to the basic profile field and the extended profile field.

6. A method of claim 1, wherein the requested content includes a keyword and the search includes a textual search of the profile fields based on the keyword, the method further comprising:

causing, at least in part, transmission of the search result.

7. A method of claim 1, wherein the profile field is further associated with a profile identifier that corresponds to one or more of the data structures, and the profile index is searched based on a comparison of the entity identifier and the access control field, the profile identifier being only associated with the entity identifier in one of the data structures.

8. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive a query specifying an entity identifier and requested content;

cause, at least in part, a search based on the entity identifier of a profile index of data structures, each specifying a profile field that is associated with an access control field to yield a search result; and

indicate access rights to the requested content for the entity identifier,

wherein the data structures further include the profile field and the access control field.

9. An apparatus of claim 8, wherein the apparatus is further caused, at least in part, to:

retrieve the requested content based on the access rights, wherein the search yields only the search results that are indicated to have access.

10. An apparatus of claim 8, wherein the profile index is searched based on a comparison of the entity identifier and the access control field.

11. An apparatus of claim 8, wherein the access control field includes a plurality of entity identifiers.

12. An apparatus of claim 11, wherein the profile field is a basic profile field and the data structure further includes an extended profile field, and wherein the access control field is utilized to specify access rights to the basic profile field and the extended profile field.

13. An apparatus of claim 11, wherein the requested content includes a keyword, the search includes a textual search of the profile fields based on the keyword, and the apparatus is further caused, at least in part, to:

cause, at least in part, transmission of the search result.

14. An apparatus of claim 11, wherein the profile field is further associated with a profile identifier that corresponds to one or more of the data structures, and the profile index is searched based on a comparison of the entity identifier and the access control field, the profile identifier being only associated with the entity identifier in one of the data structures.

15. A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

receiving a query specifying an entity identifier and requested content;

causing, at least in part, a search based on the entity identifier of a profile index of data structures, each specifying a profile field that is associated with an access control field to yield a search result; and

indicating access rights to the requested content for the entity identifier,

wherein the data structures further include the profile field and the access control field.

16. A computer-readable storage medium of claim 15, wherein the apparatus is caused, at least in part, to further perform:

retrieving the requested content based on the access rights, wherein the search yields only the search results that are indicated to have access.

17. A computer-readable storage medium of claim 15, wherein the profile index is searched based on a comparison of the entity identifier and the access control field.

18. A computer-readable storage medium of claim 15, wherein the access control field includes a plurality of entity identifiers.

19. A computer-readable storage medium of claim 18, wherein the profile field is a basic profile field and the data structure further includes an extended profile field, and wherein the access control field is utilized to specify access rights to the basic profile field and the extended profile field.

20. A computer-readable storage medium of claim 15, wherein the requested content includes a keyword, the search includes a textual search of the profile fields based on the keyword, and wherein the apparatus is caused, at least in part, to further perform:

causing, at least in part, transmission of the search result.
