<h2>Use tags</h2>

<p><a href="https://stats.stackexchange.com/help/tagging">Tags</a> allow us to sort and filter questions into categories that we are interested in. If you tag your question well, you will increase your chance that an expert in your particular problem will see your question.</p>

<p>When you are done assigning good tags, <em>don't post your question yet</em>. Instead, search through previous questions carrying your tags. You can do this simply by putting all your tags surrounded by "[]" in the search box. <a href="https://stats.stackexchange.com/questions/tagged/clustering+validation?sort=votes&amp;pageSize=50">Here is an example.</a> Chances are you will find something that already answers your question. (If you do, don't forget to upvote the question and answer so the process improves further.)</p>
