Alert conditions referring to different target servers

[yan0s]

Hello,
is there an easy way to have an ALERT with conditions for 2 (or more) different target servers?
Or is it possible to combine alerts with AND/OR operators?

This doesn't work:
metric1{instance="SERVER1"} > 10 AND metric2{instance="SERVER2"} > 20

My solution so far is something like this:
vector(scalar(metric1{instance="SERVER1"} > BOOL 10) * scalar(metric2{instance="SERVER2"} > BOOL 20)) == 1

Also, is there a thorough documentation for PromQL available somewhere?

Thank you in advance

What I am asking is actually possible like this:

metric1{instance="SERVER1"} > 10 AND ignoring(instance) metric2{instance="SERVER2"} > 10
