+
+This module allows to define custom filters in the search views for an specific
+field belonging to the document or any other related document.
+
+This nature makes the definition quite technical, but once done, it adds the
+element in the UI for regular user use.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Configuration
+=============
+
+#. Go to *Settings > Technical > User Interface > Custom Field Filters*.
+#. Create a new record, and define following information:
+
+   * The **Model** for which you are defining the filter. It will appear in all
+     the search views of this model.
+   * The label you want to see on the search line on the **Name** field. This
+     field allows translations for proper UI in different languages.
+   * The **Expression**, which is the field chain string with dot notation.
+     Examples: `product_id`, `product_id.seller_ids.name`, `partner_id.lang`.
+   * Optionally, you can fill **Position After** for indicating after which
+     existing field (technical name) the filter will appear. If empty or not
+     found, the filter will be added at the end.
+#. You can reorder records for determining sorting for multiple filters for the
+   same model with the arrow handle in the left part.
+
+Usage
+=====
+
+#. Go to the menu entry for which you have defined the custom field filter.
+#. On the search bar, type anything.
+#. In the filter list, you will see the line for the element you have defined.
+
+As demo data, a custom field filter is included for sample purposes:
+
+.. image:: https://raw.githubusercontent.com/OCA/server-ux/12.0/base_search_custom_field_filter/static/src/img/ir_ui_custom_field_filter.png
+
+Steps for trying this sample:
+
+#. Install `contacts` module.
+#. Go to *Contacts*.
+#. Type "english" and you'll find the filter "Language" at the end:

+<p>This module allows to define custom filters in the search views for an specific
+field belonging to the document or any other related document.</p>
+<p>This nature makes the definition quite technical, but once done, it adds the
+element in the UI for regular user use.</p>

+<li>Go to <em>Settings &gt; Technical &gt; User Interface &gt; Custom Field Filters</em>.</li>
+<li>Create a new record, and define following information:<ul>
+<li>The <strong>Model</strong> for which you are defining the filter. It will appear in all
+the search views of this model.</li>
+<li>The label you want to see on the search line on the <strong>Name</strong> field. This
+field allows translations for proper UI in different languages.</li>
+<li>The <strong>Expression</strong>, which is the field chain string with dot notation.
+Examples: <cite>product_id</cite>, <cite>product_id.seller_ids.name</cite>, <cite>partner_id.lang</cite>.</li>
+<li>Optionally, you can fill <strong>Position After</strong> for indicating after which
+existing field (technical name) the filter will appear. If empty or not
+found, the filter will be added at the end.</li>

+<li>In the filter list, you will see the line for the element you have defined.</li>

+<p>As demo data, a custom field filter is included for sample purposes:</p>

+<p>Steps for trying this sample:</p>
+<ol class="arabic simple">
+<li>Install <cite>contacts</cite> module.</li>
+<li>Go to <em>Contacts</em>.</li>
+<li>Type “english” and you’ll find the filter “Language” at the end:</li>
