搜索:搜索选项从 MarkLogic 7 迁移到版本 8

Question

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，并且我遇到了有关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，但没有奏效。当我在查询控制台网页中运行以下代码时，连接断开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 ML 8 后，我所有的数据库都被识别出来，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!

xquery version "1.0-ml";

正如 Joe 指出的那样，服务器可能会崩溃并自动重新启动。查询 ErrorLog.txt来验证这一点。确保您拥有 very latest release : 现在是 8.0-1.1。

测试用例做 不是 使用 8.0-1.1 和必要的索引设置在我的笔记本电脑上崩溃。但是我没有任何匹配的文件，所以它的作用不大。这可能意味着崩溃(如果确实如此)也需要您的一些内容。您可以尝试使用空数据库来验证这一点，然后尝试确定问题是否与特定的文档集有关。

如果问题仍然存在，contact support报告它。
