我有以下简单表达式expr=shortestPath(core_data,from="https://mycompany.com/id/ARMP/AM/GT/ST/CCS1/01/03/05/96/96",to="https://mycompany.com/id/ARMP/AM/GT/ST/CCS1/01/03/IS/02",edge="id=link_ss",maxDepth="4")
这就产生了一个错误。

让我进一步解释：我使用的链接字段是id(单值(和link_ss(多值(。根据我使用的顺序(id=link_ss或link_ss=id(，我会得到不同的错误。CCD_ 6或上面的一个。但请注意，解析错误已经包含了与原始ID不同的ID。因此，当在图中爬行时，错误确实会在内部发生。上面的查询确实不起作用，但在id周围加双引号有帮助，即link_ss:("https://mycomany.com/id/STL/KG1/pk_67_8/TS_67_8_5152_4")确实起的作用
谢谢！
我做了一些实验，似乎你必须逃离"中的冒号(：(；从"；字段，但不在"；至"；流式表达式的字段。只需在"；从"；领域例如：
shortestPath(oana,from="http://google.com",to="http://oana1.com",edge="link_from=link_to",maxDepth="1")
