Adobe InDesign CS2: search for text replacing with inline graphics

Hello,
I’m trying to understand how to tell InDesign to search for a string (i.e. “Coca Cola”) and replace it with a file (i.e. “Coca cola.eps”) as an inline graphic. The eps could be in a library, on the pasteboard, on the hard disk, wherever.
I tried and tried, but keep on returning errors, like “Invalid value for parameter ‘replacing with’ of event ‘search’. Expected string, but received asset.”.

I just think InDesign synthax is a bit complicated sometimes to address in the correct order…
Thank you in advance,
Guido
