<p>With the <em>SQL engines</em> you can bind SQL databases into SearXNG. The following
|
||
Relational Database Management System (RDBMS) are supported:</p>
|
||
<ul class="simple">
|
||
<li><p><a class="reference internal" href="#engine-sqlite"><span class="std std-ref">SQLite</span></a></p></li>
|
||
<li><p><a class="reference internal" href="#engine-postgresql"><span class="std std-ref">PostgreSQL</span></a></p></li>
|
||
<li><p><a class="reference internal" href="#engine-mysql-server"><span class="std std-ref">MySQL</span></a> & <a class="reference internal" href="#engine-mariadb-server"><span class="std std-ref">MariaDB</span></a></p></li>
|
||
</ul>
|
||
<p>All of the engines above are just commented out in the <a class="extlink-origin reference external" href="https://github.com/searxng/searxng/blob/master/searx/settings.yml">settings.yml</a>, as you have to set the required attributes for the
|
||
engines, e.g. <code class="docutils literal notranslate"><span class="pre">database:</span></code> …</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">...</span>
|

<span class="w"> </span><span class="nt">engine</span><span class="p">:</span><span class="w"> </span><span class="p p-Indicator">{</span><span class="nv">sqlite|postgresql|mysql_server</span><span class="p p-Indicator">}</span>
|

|
||
</pre></div>
|
||
</div>
|
||
<p>By default, the engines use the <code class="docutils literal notranslate"><span class="pre">key-value</span></code> template for displaying results /
|
||
see <a class="extlink-origin reference external" href="https://github.com/searxng/searxng/blob/master/searx/templates/simple/result_templates/key-value.html">simple</a>
|
||
theme. If you are not satisfied with the original result layout, you can use
|
||
your own template, set <code class="docutils literal notranslate"><span class="pre">result_template</span></code> attribute to <code class="docutils literal notranslate"><span class="pre">{template_name}</span></code> and
|
||
place the templates at:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">searx</span><span class="o">/</span><span class="n">templates</span><span class="o">/</span><span class="p">{</span><span class="n">theme_name</span><span class="p">}</span><span class="o">/</span><span class="n">result_templates</span><span class="o">/</span><span class="p">{</span><span class="n">template_name</span><span class="p">}</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>If you do not wish 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>For using <a class="reference internal" href="#engine-postgresql"><span class="std std-ref">PostgreSQL</span></a> or <a class="reference internal" href="#engine-mysql-server"><span class="std std-ref">MySQL</span></a> you need to
|

install additional packages in Python’s Virtual Environment of your SearXNG
|
||
instance. To switch into the environment (<a class="reference internal" href="../../../admin/installation-searxng.html#searxng-src"><span class="std std-ref">Install SearXNG & dependencies</span></a>) you can use
|
||
<a class="reference internal" href="../../../utils/searxng.sh.html#searxng-sh"><span class="std std-ref">utils/searxng.sh</span></a>:</p>
|
||

|
||
<p>The configuration of the new database engines are similar. You must put a valid
|
||
SQL-SELECT query in <code class="docutils literal notranslate"><span class="pre">query_str</span></code>. At the moment you can only bind at most one
|
||
parameter in your query. By setting the attribute <code class="docutils literal notranslate"><span class="pre">limit</span></code> you can define how
|
||
many results you want from the SQL server. Basically, it is the same as the
|
||
<code class="docutils literal notranslate"><span class="pre">LIMIT</span></code> keyword in SQL.</p>
|
||
<p>Please, do not include <code class="docutils literal notranslate"><span class="pre">LIMIT</span></code> or <code class="docutils literal notranslate"><span class="pre">OFFSET</span></code> in your SQL query as the engines
|
||
rely on these keywords during paging. If you want to configure the number of
|
||
returned results use the option <code class="docutils literal notranslate"><span class="pre">limit</span></code>.</p>
