There is a much easier way to do this. Just fill in the words directly into the table qa_words and set two values to 1!
Sample-Insert-Script:
INSERT IGNORE INTO qa_words SET word='zypern', titlecount=0,contentcount=0,tagwordcount=1,tagcount=1;
The word has to be in lowercase then everything works fine. I filled about 4.800 words into the database!
