 # CHANGELOG
 
-## (yet) Unreleased
+## 0.2.1
 * Fix count method to work with select statements under Rails 4.1. Thanks to [Jason Mitchell](https://github.com/mitchej123) for the contribution.
 * Edits to `README` documentation about the `options` hash. Thanks to [Jonathan E Hogue](https://github.com/hoguej) for pointing out that previous documentation was confusing and didn't address its usage properly.
 * Edits to `README` documentation on complex model queries inside the `get_raw_records` method. A round of applause to [Zoltan Paulovics](https://github.com/zpaulovics) for contributing this awesome piece of documentation. :smile:
 * Adds typecast step to `search_condition` method, so now we support having non-text columns inside the `searchable_columns` array.
 * Adds support for multi-column sorting and multi-term search. Thanks to [Zoltan Paulovics](https://github.com/zpaulovics) for contributing this feature.
+* Adds optional config initializer, so we can have a base to typecast non text-based columns and perform searches depending on the use of `:mysql2`, `:sqlite3` or `:pg`. Thanks to [M. Saiqul Haq](https://github.com/saiqulhaq) for contributing this feature.

 ### Additional Notes
 
+#### Searching on non text-based columns
+
+It always comes the time when you need to add a non-string/non-text based column to the `@searchable_columns` array, so you can perform searches against these column types (example: numeric, date, time).
+
+We recently added the ability to (automatically) typecast these column types and have this scenario covered. Please note however, if you are using something different from `postgre` (with the `:pg` gem), like `mysql` or `sqlite`, then you need to add an initializer in your application's `config/initializers` directory.
+
+If you don't perform this step (again, if using something different from `postgre`), your database will complain that it does not understand the default typecast used to enable such searches.
+
+You have two options to create this initializer:
+
+* use the provided (and recommended) generator (and then just edit the file);
+* create the file from scratch.
+
+To use the generator, from the terminal execute:
+
+```
+$ bundle exec rails generate datatable:config
+```
+
+Doing so, will create the `config/initializers/ajax_datatables_rails.rb` file with the following content:
+
+```ruby
+AjaxDatatablesRails.configure do |config|
+  # available options for db_adapter are: :pg, :mysql2, :sqlite3
+  # config.db_adapter = :pg
+end
+```
+
+Uncomment the `config.db_adapter` line and set the corresponding value to your
+database and gem. This is all you need.
+
+If you want to make the file from scratch, just copy the above code block into a file inside the `config/initializers` directory.
+
+
 #### Using view helpers
 
 Sometimes you'll need to use view helper methods like `link_to`, `h`, `mailto`, `edit_resource_path` in the returned JSON representation returned by the `data` method.
