Catalog empty while reindexing

[OvalMedia]

During the index process the catalog ist empty and products reappear when done. There are no errors or anything. But since indexing does take a while (lots of products) it is quite annoying. Is there anything I can do about it?

Thank you

The indexer first clears the table completely OR removes the records prior to rebuilding the index. This is clearly the cause. Wouldn't it be smarter to do a update or replace on those records and delete orphans after that?

I agree with @DocOlson
