You could issue an arsdoc delete command -- that will remove the metadata from the database, effectively erasing the document from searches. Then you could re-load the two files.
However, I'd like to warn against making this too easy for the team that provides you data. The minute they find out you can selectively remove documents and replace them with new loads, the pressure is off them to do proper QA and ensure the data they send you is correct, and the pressure moves to you to fix the problems they create. One way to do this is to require the authorization of someone very senior to allow you to selectively delete documents from CMOD -- because for many companies, CMOD stores the legal record for the company -- and deleting data creates questions about the accuracy of the data pulled from CMOD.
