How do I make search only search in post content?

Question

I want to have two search bars, one which works normally and one that searchs only in the post content but I can't even find the code of the search funtion to create the second.

Can I use a plugin to make my search function only search in post content? Thanks in advance

This line in $wp_query might be of interest:

$where = apply_filters_ref_array('posts_where', array( $where, &$this ) );

You could probably use a filter to toss in an additional post_type = 'post'. Something like:

function search_where($where, &$wp_query) {
  if ($wp_query->is_search)
    where .= ' AND post_type = 'post';
  return $where;
}
add_filter('posts_where', 'search_where', 10, 2);
