<p>Administrators might find themselves wanting to integrate locally running search
engines. The following ones are supported for now:</p>
<ul class="simple">
<li><p><a class="reference external" href="https://www.elastic.co/elasticsearch/">Elasticsearch</a></p></li>
<li><p><a class="reference external" href="https://www.meilisearch.com">Meilisearch</a></p></li>
<li><p><a class="reference external" href="https://solr.apache.org">Solr</a></p></li>
</ul>
<p>Each search engine is powerful, capable of full-text search. All of the engines
above are added to <code class="docutils literal notranslate"><span class="pre">settings.yml</span></code> just commented out, as you have to
<code class="docutils literal notranslate"><span class="pre">base_url</span></code> for all them.</p>
<p>Please note that if you are not using HTTPS to access these engines, you have to
enable HTTP requests by setting <code class="docutils literal notranslate"><span class="pre">enable_http</span></code> to <code class="docutils literal notranslate"><span class="pre">True</span></code>.</p>
<p>Furthermore, if you do not want to expose these engines on a public instance,
you can still add them and limit the access by setting <code class="docutils literal notranslate"><span class="pre">tokens</span></code> as described
in section <a class="reference internal" href="../../../admin/settings/settings_engine.html#private-engines"><span class="std std-ref">Private Engines (tokens)</span></a>.</p>

<p><a class="reference external" href="https://www.meilisearch.com">MeiliSearch</a> is aimed at individuals and small companies. It is designed for
small-scale (less than 10 million documents) data collections. E.g. it is great
for storing web pages you have visited and searching in the contents later.</p>
<p>The engine supports faceted search, so you can search in a subset of documents
of the collection. Furthermore, you can search in <a class="reference external" href="https://www.meilisearch.com">MeiliSearch</a> instances that
require authentication by setting <code class="docutils literal notranslate"><span class="pre">auth_token</span></code>.</p>

<p><a class="reference external" href="https://www.elastic.co/elasticsearch/">Elasticsearch</a> supports numerous ways to query the data it is storing. At the
moment the engine supports the most popular search methods (<code class="docutils literal notranslate"><span class="pre">query_type</span></code>):</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">match</span></code>,</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">terms</span></code>.</p></li>
</ul>
<p>If none of the methods fit your use case, you can select <code class="docutils literal notranslate"><span class="pre">custom</span></code> query type
and provide the JSON payload to submit to Elasticsearch in
<code class="docutils literal notranslate"><span class="pre">custom_query_json</span></code>.</p>
