该项目是否解决了promql存在四种运算符的问题

[sunism]

prometheus有以下4中运算符
=: Select labels that are exactly equal to the provided string.
!=: Select labels that are not equal to the provided string.
=: Select labels that regex-match the provided string.
!: Select labels that do not regex-match the provided string.
我看代码中在查询时，直接多lable进行拼接，并没有判断运算符的不同。
例如：
up{host="localhost",instance="localhost:8080",job!="cadvisor", sunzheng!"nihao"}
这种请求发送到后台后，会有type字段。目前该项目只有=，这种情况，其他三种条件并没有解决
请求后续有解决码？
