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.

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>`_)
