java client 3.6.x 遇到的bug

要实现的功能为

match (m) 
where  (m.q10000 is not null OR m.q10001 is not null )
AND id(m)=='100000000017700' 
return id(m) as mid,m.q10000 IS NOT NULL as q10000,m.PRO001.value as PRO001

在studio中正常运行,但到java client返回就为空.

测试下来 match有个提前限制java client返回就正常, 但这样不满足我的需求

match (m: Xtag) 
where  m.q10000 is not null 
AND id(m)=='100000000017700' 
return id(m) as mid,m.q10000 IS NOT NULL as q10000,m.PRO001.value as PRO001

后来改成如下才能正常运行

match (m) 
where 'q10000' in labels(m) AND id(m)=='100000000017700' 
return id(m) as mid,m.q10000 IS NOT NULL as q10000,m.PRO001.value as PRO001
