<p>I guess the result of this idea would not work as expected. It indeed could increase the probability of such posts being found, but would that stop duplicate questions being asked?</p>

<p>My hypothesis is that users who are asking recurrent duplicates do not perform at least a minimum search before posting them.</p>

<p>One partial solution would be to edit the question's title (when it is confusing or disruptive) to reflect more accurately what the post is about. <a href="https://meta.stackexchange.com/questions/10647/writing-a-good-title">This</a> post contains useful hints for writing SE titles (perhaps we could add something from it to our own <a href="https://stats.meta.stackexchange.com/questions/1479/how-to-ask-a-good-question-on-crossvalidated/1483#comment6406_1483">faq question post</a>).</p>
