<p>We can sort of do some of these with existing tools:</p> <blockquote> <ul> <li>A way to filter the SF site to only see questions from users with a rep higher than x</li> <li>A way to filter out questions if the user asking is unregistered</li> <li>A way to filter out questions if the user has a rep less than 200 on SF but higher than 200 on SO</li> </ul> </blockquote> <p>These are unlikely to ever appear as an official tool.<br> The basic concept of Stack Exchange sites is that crap gets seen by a large number of people, declared to be crap, and closed. If we allowed filtering by rep there would be a pile of crap from 1-rep accounts that nobody ever sees (except the 1-rep account holders who don't have the filter privilege). </p> <p>Basically this would make things <strong>look</strong> nicer for most of the site regulars in the 10k and 20k+ range, but the quality problem would get worse for everyone else (and our "% Answered" statistic would go completely to shit because nobody would be trawling through the muck to answer the genuinely good questions).</p> <p><em><strong>What we can do is filter by question score</em></strong> -- Check out <a href="http://serverfault.com/help/searching">the slightly improved Search documentation</a> for details.<br> You can create and bookmark search queries to use as your Server Fault homepage. Of course this relies on someone actually reviewing the questions in an unfiltered view <strong>and upvoting the good ones / downvoting the lousy ones (again we're back to "The site works better when smart people help get rid of the crap).</strong></p> <p>(That last part was bolded by Ward because - once again - the solution is MOAR Voting!)</p> <hr> <blockquote> <p>A way to filter out questions with tags that are of no interest or I have no expertise in</p> </blockquote> <p>We have <a href="http://meta.stackexchange.com/questions/19173/what-do-favorite-tags-and-ignored-tags-do">Ignored Tags</a> for this. I suggest using the default "faded out" rather than the optional "completely hidden" mode, because you never know when you'll find something useful on a post tagged <a href="http://serverfault.com/questions/tagged/windows" class="post-tag" title="show questions tagged 'windows'" rel="tag">windows</a>.</p> <hr> <blockquote> <p>A way to combine, mix/match filters, and/or, etc.</p> </blockquote> <p>The two tools we do have (Search and Ignored Tags) stack, so this is basically "combined by default".</p> <hr> <p>I know none of these are really optimal solutions, but they're at least a starting place.<br> If additional search operators would be useful we can definitely propose them to the Stack Exchange team.</p>
