Two ways out of your situation:If it's just index data you can completely lose that tablespace and recreate it, thenrecreate all needed indexes.

Second way is with recovery: you need to "create" that deleted file,
either byrestoring a backup or using the alter database create datafile
command.
In the first case you'd need redo from that backup until now. In second
case (create
fresh datafile) you would need all redo generated on that file since it's
original
creation (this method is rarely used).
In your case I would assume it would be faster to do the recovery since
it's just one file,
but then again it's not an option if you are not in archive mode, then just
recreate that
tablespace.
export/dmp file is not applicable here since it's index data, the dmp file
will only hold
the create index commands which you should have saved away somewhere else,
so just re-run
that script...
