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）不会检索我的自定义资产
but it doesnt work. search portlet (bundled with liferay 6.0) does not retrieve my custom asset
任何想法？谢谢
推荐答案
我的问题是通过删除/ data / lucent /下的数据来解决的。也许我的测试deleloppment已损坏我已经改变了方法也是doGetDocument，确保地图中没有设置空字段。非常感谢您的合作
My issue is solved by deleting data under /data/lucent/ Maybe my tests deleloppment was corrupted I've changed the method doGetDocument too, making sure that no empty field is set in the map. many thanks for your cooperation
