Is there any way to control and manual specification for start of teaser?. for example:
This is my test paragraph to find the solution.i need to know how to control the starting position of the teaser............<--!break-->
i want to stat my teaser from 'i need' . is it possible ?
There is no direct way to get , except you can do by using split summary feature available in Drupal
or if you have little bit knowledge in PHP you can tune the function node_teaser() in node.module for your requirements
