Query using multiples operator OR

Question

I need to write a query that use any of the different tag I define, because the historian database supports only this type of where condition. {tag="pressure" OR tag="level" OR tag="prometheus"} Is it possible to write logical binary operators?

I don´t know how to resolve this.

Our solutions would be

that_query{tag=~"pressure|level|prometheus"}
