search '/' command

[Jason Frerich]

How can I tell the search '/' command to perform a task after typing 
each letter on the pattern line. 

For Example:
/g0ee
I would like the above to execute as the following: 
/g - sendcommand(g)
0 - sendcommand(g0)
e - sendcommand(g0e)
e - sendcommand(g0ee)
After each letter is typed, I would like to send that letter(s) to a 
function call "sendcommand".
