4. The apparatus of claim 1 wherein said at least one processing platform is further configured to create a flag in connection with the query so that the subset of the plurality of application programming interface electronic documents illustrates differences between at least two of the application programming interface versions.

5. The apparatus of claim 1 wherein the retrieved application programming interface version data comprises at least one of error messages and supported attributes relevant to at least one of the application programming interface versions.

6. The apparatus of claim 1 wherein the code artifacts comprise at least one of managed object format (MOF) and management information base (MIB) code artifacts.

7. The apparatus of claim 1 wherein, in dynamically modifying the one or more of the plurality of application programming interface electronic documents in the subset, said at least one processing platform is further configured to at least one of create, update and delete one or more table entries in one or more databases specific to one or more interfaces.

8. The apparatus of claim 1 wherein said at least one processing platform is further configured to perform indexing of the document corpus, and to compute a term-document matrix from the index.

9. The apparatus of claim 1 wherein said at least one processing platform is further configured to compute highly correlated terms of the electronic documents in the document corpus.

10. The apparatus of claim 9 wherein said at least one processing platform is further configured to expand the query using the highly correlated terms.

11. The apparatus of claim 1 wherein said at least one processing platform is further configured to employ an automatic query expansion algorithm to expand the query.

12. The apparatus of claim 1 wherein said at least one processing platform is further configured to employ a ranking algorithm which ranks electronic documents of the plurality of application programming interface electronic documents corresponding to a later date higher than electronic documents of the plurality of application programming interface electronic documents corresponding to an earlier date.

13. A method comprising:

generating a document corpus comprising a plurality of application programming interface electronic documents, wherein the plurality of application programming interface electronic documents are organized according to one or more application programming interface versions;

receiving a query from one or more users seeking information corresponding to one or more application programming interfaces;

generating a subset of the plurality of application programming interface electronic documents from the database in response to the query using one or more code artifacts;

retrieving data corresponding to the one or more application programming interface versions;

dynamically modifying one or more of the plurality of application programming interface electronic documents in the subset of the plurality of application programming interface electronic documents based on the retrieved application programming interface version data; and

transmitting the subset of the plurality of application programming interface electronic documents to the one or more users in response to the query;

wherein the method is performed by at least one processing platform comprising at least one processing device comprising a processor coupled to a memory.

14. The method of claim 13 further comprising transforming the subset of the plurality of application programming interface electronic documents from one document format into one or more supported document formats.

15. The method of claim 14 further comprising formatting the query based on the one or more supported document formats.

16. The method of claim 13 further comprising creating a flag in connection with the query so that the subset of the plurality of application programming interface electronic documents illustrates differences between at least two of the application programming interface versions.

17. The method of claim 13 wherein the retrieved application programming interface version data comprises at least one of error messages and supported attributes relevant to at least one of the application programming interface versions.

18. The method of claim 13 wherein the code artifacts comprise at least one of managed object format (MOF) and management information base (MIB) code artifacts.

19. The method of claim 13 wherein dynamically modifying the one or more of the plurality of application programming interface electronic documents in the subset comprises at least one of creating, updating and deleting one or more table entries in one or more databases specific to one or more interfaces.

20. A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing platform causes said at least one processing platform to:

generate a document corpus comprising a plurality of application programming interface electronic documents, wherein the plurality of application programming interface electronic documents are organized according to one or more application programming interface versions;

receive a query from one or more users seeking information corresponding to one or more application programming interfaces;

generate a subset of the plurality of application programming interface electronic documents in response to the query using one or more code artifacts;
