+This addon provides the ability to create GIN or GiST indexes of char and text
+fields and also to use the search operator `%` in search domains. Currently
+this module doesn't change the backend search or anything else. It provides
+only the possibility to perform the fuzzy search for external addons.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Installation
+============
+
+#. The PostgreSQL extension ``pg_trgm`` should be available. In debian based
+   distribution you have to install the `postgresql-contrib` module.
+#. Install the ``pg_trgm`` extension to your database or give your postgresql
+   user the ``SUPERUSER`` right (this allows the odoo module to install the
+   extension to the database).
+
+Configuration
+=============
+
+If the odoo module is installed:
+
+#. You can define ``GIN`` and ``GiST`` indexes for `char` and `text` via
+   `Settings -> Database Structure -> Trigram Index`. The index name will
+   automatically created for new entries.
+
+Usage
+=====
+
+#. You can create an index for the `name` field of `res.partner`.
+#. In the search you can use:
+
+   ``self.env['res.partner'].search([('name', '%', 'Jon Miller)])``
+
+#. In this example the function will return positive result for `John Miller`
+   or `John Mill`.
+
+#. You can tweak the number of strings to be returned by adjusting the set
+   limit (default: 0.3). NB: Currently you have to set the limit by executing
+   the following SQL statement:
+
+   ``self.env.cr.execute("SELECT set_limit(0.2);")``
+
+For further questions read the Documentation of the
+`pg_trgm <https://www.postgresql.org/docs/current/static/pgtrgm.html>`_ module.
+
+
+Usage with demo data
+====================
+
+There are some demo data that allow you to test functionally this module
+if you are in a **demo** database. The steps are the following:
+
+#. Go to *Contacts* and type the text **Jon Smith** or **Smith John** in
+   the search box and select **Search Display Name for: ...**
+#. You will see two contacts, and they are the ones with display names
+   **John Smith** and **John Smizz**.
+
+Known issues / Roadmap
+======================
+
+* Modify the general search parts (e.g. in tree view or many2one fields)
+* Add better `order by` handling
+* This module will not be necessary from version 16 (`[IMP] Better handling of indexes #83015 <https://github.com/odoo/odoo/pull/83015>`_)
+
+Bug Tracker
+===========
+
+Bugs are tracked on `GitHub Issues <https://github.com/OCA/server-tools/issues>`_.
