Ok, in this case, it's normal that you get "t" since that the word
that is before the cursor (just before the closing parenthesis) when
you type C-x C-e.

Yes. But as mentionned by Miles, you can write a more complex
expression to select the buffer where you want to work:
$ emacsclient -e '(mapcar (function buffer-name) (buffer-list))'
("some" "buffer" "names" ...)
$ emacsclient -e '(with-current-buffer "index" (current-word nil t))'
"source"

(You could, but you must know what buffer you want.)
Why do it from the exterior? Stay with emacs. Write an emacs command.
(defun search-with-sdcv ()
(interactive)
(let ((word (current-word nil t)))
(when word
(shell-command (format "sdcv %S" word) "*sdcv output*" "*sdcv
errors*"))))
Then you may even bind that command to a key:
(global-set-key (kbd "<F12>") 'search-with-sdcv)
so you just have one key to type to initiate that search from emacs,
without leaving emacs.
