【问题描述】：
我正在尝试将用 XQuery 编写的搜索应用程序从 MarkLogic 7 迁移到版本 8，并且我遇到了关于选项中约束命名空间的已知不兼容问题。我尝试添加默认的 json/basic 命名空间，然后添加自定义命名空间，但没有成功。当我在查询控制台网页中运行以下代码时，连接会丢失并在几秒钟后重新加载。我什至重新创建了一个元素范围索引，在我安装了 ML 8 之后，我的所有数据库都被识别了，我重新索引了目标数据库。不知道还有什么问题。任何指导将不胜感激，谢谢！

【问题讨论】：
-
MarkLogic 是否正在重新启动？
ErrorLog.txt中是否有相关错误？ -
Straat 等元素是否使用带有基本配置的 json:transform() 从 JSON 键转换而来？如果是这样，则 search:element 的 ns 属性应为“marklogic.com/xdmp/json/basic”（或者 JSON 应作为本机 JSON 重新摄取，并且选项应使用 search:json-property）。
-
是的，我收到以下错误并重新启动服务器。
-
线程：ACCESS_VIOLATION # 1 0x0000000140290185 in xdmp::OnDiskFewGeoRangesLazyItemIterator::next() (ondiskrangeindexes.cpp:29299)
-
将联系支持人员。谢谢！
