Index additional information using node_api hook

I was going through one of my projects and I came to know that how simple it is to insert additional information into your site's search indexes using hook_nodeapi. A comprehensive details about hook_nodeapi can be found here.

Following are the steps involved to make this happen:

  • Create a module that implements hook_nodeapi, lets say example_nodeapi()

function example_nodeapi($node, $op) {
  // Function definition here
}
