Filter words in panel triggers (grafana-zabbix)

Hi…

I´m trying filter out some triggers in panel triggers of app grafana-zabbix.
In my test I try:
/(?!volume)/
/(?!volume)./
/.
(?!volume).*/
/(?!\s(volume))/
But it return nothing or all triggers.
If I filter
/(volume)/
it works, and in panel triggers show only trigger with word volume.
What am I doing wrong?

I found the expression.

/^((?!word).)*$/
