<p>Are you familiar with the <a href="https://stats.stackexchange.com/help/searching">Advanced Search</a> options? They help a lot filtering questions (and answers).</p>

<p>For example, if you want to search for questions with accepted answer type in the <a href="https://stats.stackexchange.com/search?q=">search field box</a>: </p>

<p><code>hasaccepted:1</code> (<a href="https://stats.stackexchange.com/search?q=hasaccepted%3A1">click me</a>).</p>

<p>To search for questions with accepted answers and which were not closed or put on hold type:</p>

<p><code>hasaccepted:1 closed:0</code> and so on with other options.</p>

<p>Unfortunately, there is not a current advanced search option customized for threads with awarded bounties. As I think you already know one can search for current open bounties in the <a href="https://stats.stackexchange.com/questions?sort=featured">featured</a> tab.</p>

<p>One option for searching bounties on old threads is the <a href="http://data.stackexchange.com/stats/query/170307/top-200-bounties-by-bounty-amount" rel="nofollow noreferrer">Stack Exchange Data Explorer</a>.
The link is a query which should retrieve the top 200 bounties (regarding amount of reputation). It is not very organized though. Some threads (specially the oldest, for example, from 2010) do not contain bounties. Maybe in such situations, it was opened a bounty but they were not awarded. If you go to the top bounties (500 rep, 200 rep) you will see they were actually awarded.</p>

<p>Hope this helps you to get started. Good luck. Good learning.</p>
