Search Liferay 6.2执行索引搜索时发生GA6错误

前提是我们最近从Liferay GA2升级到了Liferay GA6，在Liferay GA2中，我们在索引搜索过程中从来没有出现过任何错误，实际上大部分时间搜索都不会出现问题，但有时在索引搜索过程中，我们会出现以下错误，有人知道是否有修复程序可用于删除这些问题吗？需要明确的是，我们知道这些错误本身意味着什么，但考虑到它们不是发生在我们的代码中，而是发生在liferay portal代码中，我们不知道原因是什么。 错误从这行代码中的调用开始：

BooleanQuery baseQuery = indexer.getFullQuery(searchContext);

谢谢
