Try to perform an insert call with IO-area containing just the key you want to find. If you receive status code II (duplicate segment) the segment you searched for is there. Of course this only applies when the key/sequence value is defined unique in your DBD. You then also should know the path where to insert. This might be a faster way since the index is checked before insertion instead of segment-IO at a GU.
