<h1>Query your local search engines<a class="headerlink" href="#query-your-local-search-engines" title="Permalink to this headline"></a></h1>
<p>From now on, searx lets you to query your locally running search engines. The following
ones are supported 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>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>Futhermore, 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 the <a class="reference external" href="private-engines.html#private-engines">blog post about
private engines</a>.</p>
<div class="section" id="configuring-searx-for-search-engines">
<h2>Configuring searx for search engines<a class="headerlink" href="#configuring-searx-for-search-engines" title="Permalink to this headline"></a></h2>
<p>Each search engine is powerful, capable of full-text search.</p>
<div class="section" id="elasticsearch">
<h3>Elasticsearch<a class="headerlink" href="#elasticsearch" title="Permalink to this headline"></a></h3>
<p>Elasticsearch 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">match</span></code>, <code class="docutils literal notranslate"><span class="pre">simple_query_string</span></code>, <code class="docutils literal notranslate"><span class="pre">term</span></code> and <code class="docutils literal notranslate"><span class="pre">terms</span></code>.</p>
<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
searx has to submit to Elasticsearch in <code class="docutils literal notranslate"><span class="pre">custom_query_json</span></code>.</p>
<p>The following is an example configuration for an Elasticsearch instance with authentication
configured to read from <code class="docutils literal notranslate"><span class="pre">my-index</span></code> index.</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="p p-Indicator">-</span> <span class="nt">name </span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">elasticsearch</span>

<div class="section" id="meilisearch">
<h3>Meilisearch<a class="headerlink" href="#meilisearch" title="Permalink to this headline"></a></h3>
<p>This search engine 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.
Futhermore, you can search in Meilisearch instances that require authentication by setting <code class="docutils literal notranslate"><span class="pre">auth_token</span></code>.</p>
<p>Here is a simple example to query a Meilisearch instance:</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="p p-Indicator">-</span> <span class="nt">name </span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">meilisearch</span>
<span class="nt">engine </span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">meilisearch</span>
<span class="nt">shortcut</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">mes</span>
<span class="nt">base_url </span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">http://localhost:7700</span>
<span class="nt">index </span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">my-index</span>

<div class="section" id="solr">
<h3>Solr<a class="headerlink" href="#solr" title="Permalink to this headline"></a></h3>
<p>Solr is a popular search engine based on Lucene, just like Elasticsearch.
But instead of searching in indices, you can search in collections.</p>
<p>This is an example configuration for searching in the collection <code class="docutils literal notranslate"><span class="pre">my-collection</span></code> and get
the results in ascending order.</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="p p-Indicator">-</span> <span class="nt">name </span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">solr</span>
