The answer given by @Tanghus could help by making more relevant search results visible to posters to see more easily if similar question has been asked before. It would be even better if a special duplicate search mode would be activated when rhe question is ready but not yet submitted to forum. The search would reveal the existance of similar questions based on header, tags, and question text (as proposef by @tanghus). The difference here is that the poster would need to confirm that no immediate duplicates were found, and just then the question would get posted.
Also, yet another level of duplicate detection could be implemented so that new question wouldn't immediately be votable and commentable by others but just after a grace-period (e.g. 2 hours) during which others could only report it as duplicate and close it (the poster could edit, close or delete question normally). After grace-period question would be fully accessable to othrrs too. This way questions wouldn't collect many votes or comments before detected as duplicates, and the need to merge duplicates could be avoided.
