<p>Search with <tt class="docutils literal">Searx</tt>/<tt class="docutils literal">SearXNG</tt> instances without the need for a complex
web-browser.</p>
<p>Searx-Qt is a desktop application that lets you search on
public <tt class="docutils literal">SearXNG</tt> instances listed on <tt class="docutils literal"><span class="pre">https://searx.space</span></tt> (or you
can add <tt class="docutils literal">Searx</tt> or <tt class="docutils literal">SearXNG</tt> instance urls manually).</p>
<p>The aim of the project is to preform search operations on <tt class="docutils literal">Searx</tt>/
<tt class="docutils literal">SearXNG</tt> instances with the use of their API and without the need for a
complex web-browser. <tt class="docutils literal"><span class="pre">Searx-Qt</span></tt> will do the bare minimum of what is
required to search, no cookies and no javascript. Just render a
<tt class="docutils literal">Searx</tt>/<tt class="docutils literal">SearXNG</tt> API request to something usefull.</p>
<p>Since version <cite>0.2</cite> it is also possible to manage your own (private?)
instances with the use of a 'user' profile.</p>

<p>The <tt class="docutils literal">Searx</tt> project is no longer maintained but for now <tt class="docutils literal"><span class="pre">Searx-Qt</span></tt>

<p>The default language is English.</p>
<p>Since version <cite>0.2</cite> Searx-Qt is able (application-wise, not search results) to
be fully translated with the use of gettext and <cite>.po .pot</cite> files. However the
only translation available currently is for the Dutch language. If you like to
translate Searx-Qt in your language then you can find a example of how to do
that in the <a class="reference internal" href="#development">development section</a>. Please consider opening a
PR on <tt class="docutils literal"><span class="pre">https://notabug.org/CYBERDEViL/searx-qt</span></tt> after your translation has
finished.</p>

<p>It is always recommended to let the package-manager of your system
do the installing of software, so your package-manager will keep
track of files installed. Only use <tt class="docutils literal">setup.py</tt> directly if you
know what you are doing.</p>
<p>Since Searx-Qt isn't available in any GNU/Linux distribution (yet?); the
best option is to create a package for your distribution yourself from the
latest release. This will also mean that you have to manually update
Searx-Qt if there is a new version available.</p>

named <cite>Tor</cite> which has different proxy and stats2 settings then you normal
profile.</p>
<dl class="docutils">

<p>The profile type names maybe changed to something better, suggestions are

<p>Create a <cite>Stats2</cite> profile if you wish to get/update a list of Searx-instances
from a <cite>Searx-Stats2</cite> instance. For example the default <cite>https://searx.space</cite>.</p>

<p>Guard can put instances on a timeout or the blacklist when they are failing.</p>
<p>When the Guard rules are set properly, searches will be quicker over time
since failing instances are not used anymore. This reduces the chance of
requesting a search query to a instance that probably will fail again. Also
some instances block our request for whatever reason they have, and there is
no standard response so they all may (and many will) respond diffrently (Thus
we can not properly detect when we may use the API and when not).</p>
<blockquote>
<ul class="simple">

<li>Below the <tt class="docutils literal">Store log</tt> option is a spinbox that defines for how long log entries will be stored (in days).</li>

<p>Search period you like results from. Options are <tt class="docutils literal">Last day</tt>,
<tt class="docutils literal">Last week</tt>, <tt class="docutils literal">Last month</tt> or <tt class="docutils literal">Last year</tt>.</p>
</div>
<div class="section" id="language">
<span id="usage-search-options-language"></span><h4>Language</h4>
<p>If you want results in a specific language than you can select one here. The
set language will persist on restart.</p>
<p>Since Searx-Qt 0.3 there is a option to mark languages a favorites. Favorites
will appear on the top of the combobox list so you won't have to scroll.</p>
<p>Adding a language to favorite can be done by hovering the language and
pressing the spacebar on your keyboard. Removing a favorite works the same,
hover the favorite language and press the spacebar on your keyboard.</p>

<p>Searx-Qt will try to find a translation for your system locale and use that
when found.</p>
<p>To test translations the system locale should be installed for that language,
it doesn't have to be set for testing since we can easly override the <tt class="docutils literal">LANG</tt>
environment variable before executing Searx-Qt.</p>
<p><strong>NOTE</strong>: The examples below are for a Dutch language translation, you
should replace <tt class="docutils literal">nl_NL</tt> with the i18n locale ID of the language you whish to
translate.</p>
