            documents.add(document);
        }

        SearchEngineUtil.updateDocuments(companyId, documents);
    }
}

这是我的 liferay portlet.xml:

<indexer-class>path package .ProjetIndexer</indexer-class>   

但它不起作用。搜索 portlet(与 liferay 6.0 捆绑在一起)不检索我的自定义 Assets

有什么想法吗？谢谢

我的问题通过删除/data/lucent/下的数据得到解决。也许我的测试删除已损坏我也更改了 doGetDocument 方法，确保 map 中没有设置空字段。非常感谢您的合作
