// Adding the teaser
if (isset($node->teaser)) {
$document->teaser = apachesolr_clean_text($node->teaser);
}
else {
// If there is no node teaser we will have to generate the teaser
// ourselves. We have to be careful to not leak the author and other
// information that is normally also not visible.
if (isset($node->body[$language][0]['safe_summary'])) {
$document->teaser = apachesolr_clean_text($node->body[$language][0]['safe_summary']);
}
else {
$document->teaser = truncate_utf8($document->content, 300, TRUE);
}
}
改成 新代码
// Adding the teaser
if (isset($node->teaser)) {
$document->teaser = apachesolr_clean_text($node->teaser);
}
else {
// If there is no node teaser we will have to generate the teaser
// ourselves. We have to be careful to not leak the author and other
// information that is normally also not visible.
if (isset($node->body[$language][0]['safe_summary']) || isset($node->body['und'][0]['safe_summary'])) {
$str_teaser = isset($node->body[$language][0]['safe_summary']) ? $node->body[$language][0]['safe_summary'] : $node->body['und'][0]['safe_summary'];
$document->teaser = apachesolr_clean_text($str_teaser);
}
else {
$document->teaser = truncate_utf8($document->content, 300, TRUE);
}
}
原代码 处主要是关于不识别语言代码,可能有问题,,所以
可能不搜 内容概要 ($node->body[$language][0]['safe_summary']),
而只搜内容的截取 truncate_utf8($document->content, 300, TRUE);
下面 也是表达的同样的意思
