[saiyxin]

Hello，when I use a filter expression contain Chinese character in ContentFilteredTopic Info to filter string，a 5085 error has popped up，but when I use the same way to filter a Numerical type，it has no error. So how to explain it? Is it supported to use Chinese lable in filter expression?

Hi saiyxin,

That is not supported. Valid characters for Identifiers of queries and filters are  'a', ..., 'z', 'A', ..., 'Z', '0', ..., '9', '_' (see "identifiers section here").  This is a Interface Definition Language specification  requirement (see section 7.2.3 "Identifiers" here).
