Description

Implementation of hook_update_index().

Code

<?php
function node_update_index() {
  $last = variable_get('node_cron_last', 0);
  $limit = (int)variable_get('search_cron_limit', 100);

  $result = db_query_range('SELECT n.nid, c.last_comment_timestamp FROM {node} n LEFT JOIN {node_comment_statistics} c ON n.nid = c.nid WHERE n.status = 1 AND n.moderate = 0 AND (n.created > %d OR n.changed > %d OR c.last_comment_timestamp > %d) ORDER BY GREATEST(n.created, n.changed, c.last_comment_timestamp) ASC', $last, $last, $last, 0, $limit);

  while ($node = db_fetch_object($result)) {
    $last_comment = $node->last_comment_timestamp;
    $node = node_load(array('nid' => $node->nid));

    // We update this variable per node in case cron times out, or if the node
    // cannot be indexed (PHP nodes which call drupal_goto, for example).
    // In rare cases this can mean a node is only partially indexed, but the
    // chances of this happening are very small.
    variable_set('node_cron_last', max($last_comment, $node->changed, $node->created));

    // Get node output (filtered and with module-specific fields).
    if (node_hook($node, 'view')) {
      node_invoke($node, 'view', false, false);
    }
    else {
      $node = node_prepare($node, false);
    }
    // Allow modules to change $node->body before viewing.
    node_invoke_nodeapi($node, 'view', false, false);

    $text = '<h1>'. check_plain($node->title) .'</h1>'. $node->body;

    // Fetch extra data normally not visible
    $extra = node_invoke_nodeapi($node, 'update index');
    foreach ($extra as $t) {
      $text .= $t;
    }

    // Update index
    search_index($node->nid, 'node', $text);
