<p dir="auto">There's no single source of reference for configuration options which makes configuring Elasticsearch awkward. <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html" rel="nofollow">https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html</a> is a good start but I believe more is omitted than included (<code class="notranslate">path.repo</code> for example).</p>
<p dir="auto">Elasticsearch needs a single page that lists every possible configuration option with an explanation of what the setting does, Django has a good example <a href="https://docs.djangoproject.com/en/1.8/ref/settings/" rel="nofollow">https://docs.djangoproject.com/en/1.8/ref/settings/</a></p>
<p dir="auto">Provide a comprehensive complete list of <strong>all</strong> settings for each es version like <a href="https://gist.github.com/jprante/7dccffa7f0c0c7576fa9">https://gist.github.com/jprante/7dccffa7f0c0c7576fa9</a> does for 1.2</p>
