<p>Linking through the <a href="https://stats.stackexchange.com/questions/tagged/multiple-comparisons">multiple-comparisons</a> tab gives a page listing 47 tagged questions (as of this moment).  The textbox in the upper right corner reads "[multiple-comparisons]".  Typing in another search term, such as "[multiple-comparisons] correlation" and pressing <strong>Enter</strong> <em>restricts</em> the search, in this case returning just 8 results.  The URL for these results is <a href="https://stats.stackexchange.com/search?q=[multiple-comparisons]+correlation">https://stats.stackexchange.com/search?q=[multiple-comparisons]+correlation</a>.</p>

<p>However, using the <em>same</em> URL for a <a href="https://stats.stackexchange.com/search?q=%5Bmultiple-comparisons%5D%20correlation">link within a comment</a> returns 390 search results!!</p>

<p>(If you link through the preceding line you will see 8 results.  If you link through the first comment below you will see all 390.)</p>
