[Orgmode] org-drill : automatic recognition of double entries

[Detlef Steuer]

I'm now using org-drll to learn some vocabulary.
Very nice package, especially together with org-capture.

After capturing words for some time it happens to catch a word as new 
for a second time. But as is the nature of unknown vocabulary you
do not remember all those new words error free.

Has anybody an idea how to recognise automatically, if a word was already 
entered in the vocabulary.org file?

Best would be if it checked the existence of a word during the capturing 
process. 

My capturing template looks like this:

  ("w" "Vocabulary" entry (file+headline "~/Norwegisch/norwegisch.org" "Vokabeln
") "* Wort \n:PROPERTIES:\n:DRILL_CARD_TYPE: twosided\n:END:\n\n**** norsk\n%^ \
n**** deutsch \n%^"))

So I'd would like to be noticed  of a doubled entry just after having
filled in  the first %^ .

Any ideas for a refined workflow appreciated.
