Dear,

From match-tag, it's stated that:

Tag的索引和属性的索引不同。如果Tag的某个属性有索引,但是Tag本身没有索引,用户无法基于该Tag执行MATCH语句。

While in create index, it mentioned that:

如果已经为"某个Tag T的属性A"建立过属性索引i_TA,则没有必要对于Tag T额外再建立一个Tag索引i_T。这是因为查询引擎可以使用i_TA来替代i_T。Edge type索引同理。但是,i_T却不能替代i_TA用于属性查找。

How should I understand this, please?
Thanks!
BR, Wey

你可以试试,应该在某个中间版本加上了属性索引替代tag索引。
所以前一句的限制就取消了。
