Related posts – associate index of Children posts with Parent posts?

  • Is it possible to associate the index of one custom post type with the post id of a different custom post type?

    Basically I have a Parent post type and Child post type. When I run a search I want to look within the Parents and Children but only return Parents that match and/or Parents who have Children that match.

    hope that makes sense .. at the end of the day I think I want to duplicate the index of Child post types, replacing the Child post ID with its Parent post ID

    Alternatively I think it would also work to completely replace the ‘doc’ column for any Child entries in the index, changing the Child post ID to its Parent post ID

    is there a hook that would let me do this?

    I’d do this with a relevanssi_hits_filter filter function that would replace the child posts with their parents. 

    add_filter(‘relevanssi_hits_filter’, ‘rlv_child_to_parent’);
function rlv_child_to_parent($hits) {
    $results = array();
    foreach ($hits[0] as $hit) {
        if ($hit is a child post) {
            $parent = get the parent post of the child;
            $results[] = $parent;
        }
        else {
            $results[] = $hit;
        }
    }
    $hits[0] = $results;
    return $hits;
}

    That’s the basic idea. You probably need to check somehow that you’re not getting duplicates in the search, but that’s the easiest way.
