Query SQL servers
|
|
=================
|
|
|
|
Now you can query SQL servers using searx. The following ones are supported:
|
|
|
|
* `PostgreSQL`_
|
|
* `MySQL`_
|
|
* `SQLite`_
|
|
|
|
All of the engines above are added to ``settings.yml`` just commented out, as you have to
|
|
set the required attributes for the engines, e.g. ``database``. By default, the engines use
|
|
``key-value`` template for displaying results. If you are not satisfied with the original result layout,
|
|
you can use your owm template by placing the template under
|
|
``searx/templates/{theme_name}/result_templates/{template_name}`` and setting
|
|
``result_template`` attribute to ``{template_name}``.
|
|
|
|
As mentioned in previous blog posts, if you do not wish to expose these engines on a
|
|
public instance, you can still add them and limit the access by setting ``tokens``
|
|
as described in the `blog post about private engines`_.
|
|
|
|
Configure the engines
|
|
=====================
|
|
|
|
The configuration of the new database engines are similar. You must put a valid
|
|
SELECT SQL query in ``query_str``. At the moment you can only bind at most
|
|
one parameter in your query. By setting the attribute ``limit`` you can
|
|
define how many results you want from the SQL server. Basically, it
|
|
is the same as the LIMIT keyword in SQL.
|
|
|
|
Please, do not include LIMIT or OFFSET 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 ``limit``.
|
|
|
|
PostgreSQL
|
|
----------
|
|
|
|
PostgreSQL is a powerful and robust open source database.
|
|
|
|
Before configuring the PostgreSQL engine, you must install the dependency ``psychopg2``.
|
|
|
|
You can find an example configuration below:
|
|
|
|
.. code:: yaml
|
|
|
|
- name : postgresql
|
|
engine : postgresql
|
|
database : my_database
|
|
username : searx
|
|
password : password
|
|
query_str : 'SELECT * from my_table WHERE my_column = %(query)s'
|
|
shortcut : psql
|
|
|
|
|
|
MySQL
|
|
-----
|
|
|
|
MySQL is said to be the most popular open source database.
|
|
|
|
Before enabling MySQL engine, you must install the package ``mysql-connector-python``.
|
|
|
|
The authentication plugin is configurable by setting ``auth_plugin`` in the attributes.
|
|
By default it is set to ``caching_sha2_password``.
|
|
|
|
This is an example configuration for querying a MySQL server:
|
|
|
|
.. code:: yaml
|
|
|
|
- name : mysql
|
|
engine : mysql_server
|
|
database : my_database
|
|
username : searx
|
|
password : password
|
|
limit : 5
|
|
query_str : 'SELECT * from my_table WHERE my_column=%(query)s'
|
|
shortcut : mysql
|
|
|
|
|
|
SQLite
|
|
------
|
|
|
|
SQLite is a small, fast and reliable SQL database engine. It does not require
|
|
any extra dependency.
|
|
|
|
You can read from your database ``my_database`` using this example configuration:
|
|
|
|
.. code:: yaml
|
|
|
|
- name : sqlite
|
|
engine : sqlite
|
|
shortcut: sq
|
|
database : my_database
|
|
query_str : 'SELECT * FROM my_table WHERE my_column=:query'
|
|
|
|
|
|
Next steps
|
|
==========
|
|
|
|
The next step is to add support for more data stores, e.g. Redis and MongoDB.
