Zend Search Lucene: Where do I put the code?

I have a CMS that I am adding Site Search functionality. The application uses the ful开发者_开发百科l Zend Framework MVC stack.

At this point if seems that I should be creating/using a Search model. All models I've created up to this point have been based on database tables. What would a Search model look like? Am I taking the wrong approach?

Basically by using Zend_Search_Lucne you will create an index of your database on to your web-server . Hence shifting load from database server to web-server (which is good thing since you can easily have many webserver but not many database server).

To build index . You treat each row of your table which you want to be searchable as a single Zend_Search_Lucene_Document in lucene . And columns becames Zend_Search_Lucene_Field . You add these documents into your index which lives on hardisk . At the time of searching you query against this index .
