indexing in KM

Hi

We are trying to create indexes on a file system repeository.The index is created fine but when we are checking in the Trex monitor for status it does not look like it has carried out any indexing on the documents.I feel that there is a step in between that I forgot.

Can anybody please tell me the steps to create a index on a file system repository.

Or any suggestion about where to look for some information on indexes would be of great help.

We are in EP5.0Sp5

Thanks

Swetha
