<p>Administrators might find themselves wanting to limit access to some of the
enabled engines on their instances. It might be because they do not want to
expose some private information through <a class="reference internal" href="../../dev/engines/index.html#offline-engines"><span class="std std-ref">Offline Engines</span></a>. Or they would
rather share engines only with their trusted friends or colleagues.</p>
<aside class="sidebar">
<p class="sidebar-title">info</p>
<p>Initial sponsored by <a class="reference external" href="https://nlnet.nl/discovery">Search and Discovery Fund</a> of <a class="reference external" href="https://nlnet.nl/">NLnet Foundation</a>.</p>
</aside>
<p>To solve this issue the concept of <em>private engines</em> exists.</p>
<p>A new option was added to engines named <cite>tokens</cite>. It expects a list of strings.
If the user making a request presents one of the tokens of an engine, they can
access information about the engine and make search requests.</p>
<p>Example configuration to restrict access to the Arch Linux Wiki engine:</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="p p-Indicator">-</span><span class="w"> </span><span class="nt">name</span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">arch linux wiki</span>
<span class="w"> </span><span class="nt">engine</span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">archlinux</span>
<span class="w"> </span><span class="nt">shortcut</span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">al</span>
<span class="w"> </span><span class="nt">tokens</span><span class="p">:</span><span class="w"> </span><span class="p p-Indicator">[</span><span class="w"> </span><span class="s">&#39;my-secret-token&#39;</span><span class="w"> </span><span class="p p-Indicator">]</span>
</pre></div>
</div>
<p>Unless a user has configured the right token, the engine is going to be hidden
from them. It is not going to be included in the list of engines on the
Preferences page and in the output of <cite>/config</cite> REST API call.</p>
<p>Tokens can be added to one’s configuration on the Preferences page under “Engine
tokens”. The input expects a comma separated list of strings.</p>
<p>The distribution of the tokens from the administrator to the users is not carved
in stone. As providing access to such engines implies that the admin knows and
trusts the user, we do not see necessary to come up with a strict process.
Instead, we would like to add guidelines to the documentation of the feature.</p>

<section id="example-multilingual-search">
<h2>Example: Multilingual Search<a class="headerlink" href="#example-multilingual-search" title="Link to this heading"></a></h2>
<p>SearXNG does not support true multilingual search. You have to use the language
prefix in your search query when searching in a different language.</p>
<p>But there is a workaround: By adding a new search engine with a different
language, SearXNG will search in your default and other language.</p>
<p>Example configuration in settings.yml for a German and English speaker:</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="nt">search</span><span class="p">:</span>
<span class="w"> </span><span class="nt">default_lang </span><span class="p">:</span><span class="w"> </span><span class="s">&quot;de&quot;</span>
<span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">...</span>
<span class="nt">engines</span><span class="p">:</span>
<span class="w"> </span><span class="p p-Indicator">-</span><span class="w"> </span><span class="nt">name </span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">google english</span>
<span class="w"> </span><span class="nt">engine </span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">google</span>
<span class="w"> </span><span class="nt">language </span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">en</span>
<span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">...</span>
</pre></div>
</div>
<p>When searching, the default google engine will return German results and
“google english” will return English results.</p>

<p>In SearXNG, plugins can be registered in the <a class="reference internal" href="../../dev/plugins/development.html#searx.plugins.PluginStorage" title="searx.plugins.PluginStorage"><code class="xref py py-obj docutils literal notranslate"><span class="pre">PluginStore</span></code></a> via a fully qualified class name.</p>
<p>A configuration (<a class="reference internal" href="../../dev/plugins/development.html#searx.plugins.PluginCfg" title="searx.plugins.PluginCfg"><code class="xref py py-obj docutils literal notranslate"><span class="pre">PluginCfg</span></code></a>) can be
transferred to the plugin, e.g. to activate it by default / <em>opt-in</em> or
<em>opt-out</em> from user’s point of view.</p>
<p>Please note that some plugins, such as the <a class="reference internal" href="../../dev/plugins/hostnames.html#hostnames-plugin"><span class="std std-ref">Hostnames</span></a> plugin,
require further configuration before they can be made available for selection.</p>
<p>By default the <a class="reference internal" href="#settings-built-in-plugins"><span class="std std-ref">built-in plugins</span></a> are loaded. To change the list
of plugins to be loaded, the value for <code class="docutils literal notranslate"><span class="pre">plugins:</span></code> in
<code class="docutils literal notranslate"><span class="pre">/etc/searxng/settings.yml</span></code> must be overwritten.</p>
<p>Following is an example that uses <a class="reference internal" href="settings.html#settings-use-default-settings"><span class="std std-ref">use_default_settings</span></a> and only
two plugins are registered: the calculator can be activated by the user and the
unit converter is active by default.</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="nt">use_default_settings</span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">true</span>

</pre></div>
</div>
<p>When using sockets, don’t forget to check the access rights on the socket:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ls</span> <span class="o">-</span><span class="n">la</span> <span class="o">/</span><span class="n">usr</span><span class="o">/</span><span class="n">local</span><span class="o">/</span><span class="n">searxng</span><span class="o">-</span><span class="n">valkey</span><span class="o">/</span><span class="n">run</span><span class="o">/</span><span class="n">valkey</span><span class="o">.</span><span class="n">sock</span>

</pre></div>
</div>
<p>In this example read/write access is given to the <em>searxng-valkey</em> group. To
get access rights to valkey instance (the socket), your SearXNG (or even your
developer) account needs to be added to the <em>searxng-valkey</em> group.</p>
