Adding search to ActiveRecord, Rails model

Adding search to a rails model using the scoped search rails plugin is a simple declaration of the desired search syntax.

In an ActiveRecored driven model, we will need to add the following declaration:

class book < ActiveRecord
...
scoped_search :on => :title

This declaration will enable search on a field called ‘title’ in the database table that is referenced by the current model.

Two search syntax will be available to the user:  free-text, for example “lorem”,  and specific search term, for example  ”title ~ ipsum”.

To enable searching for the current model by conditions on a property of a related model use the following declaration:

scoped_search :in => author, :on => :name

To change the searched property name use the following declaration

scoped_search :in => author, :on => :name,  :rename => author

The result is a search syntax where a user can type “author = oz” and get the list of books by a writer named oz.
