i assigned tags to my sensors, devices and groups. i want to search based on tags and maybe use AND and OR operations in my search syntax for example i have assigned a tag called 3850_CPU to all my 3850 switches cpu sensor and i have assigned a tag called london_branch to my london branch group. so now if i search : "3850_CPU" the result would be all 3850 cpu sensors witch is great. but now i need a search syntax like : "london_branch AND 3850_CPU" and i want to see my 3850 cpu sensor from london branch group. how can i achieve that?
