使用query_filter进行mlcp导出

问题描述

我试图将文件（从安装在计算机上的Marklogic服务器）导出到本地环境，并且出现以下错误：

mlcp.sh export -host localhost -port 8000 -username admin \
>     -password admin -mode local -output_file_path \
>     /output_dir \
> -database data-hub-FINAL -document_selector {/envelope/instance/name-entity} \
> -query_filter {"wordQuery":{"name":["Jason"]}}

我不知道我要缺少什么，我已经尝试了一次简单的导入，并且效果很好。因此，我猜该错误来自我的查询语法。

有什么想法吗？非常感谢

解决方法

https://docs.marklogic.com/guide/mlcp/export#id_66898

建议在使用-query_filter时使用选项文件，因为XML和JSON序列化查询都包含引号和其他字符，这些字符对Unix和Windows命令外壳具有特殊含义，这使得正确地对查询进行转义具有挑战性。 / p>

如果在命令行上使用-query_filter，则必须引用序列化查询，并且可能需要进行其他特殊字符转义。
