Kibana Open Distro Alerts - 2+ monitor conditions & relative triggers

hi,

currently familiarising with Open Distro Alerting Features in Kibana and wanted to ask 2 quick questions.

  1. Can triggers be relative values of total hits?
    e.x.: trigger: > 10% of total hits

  2. Can Monitors be set up for 2+ conditions?
    e.x.: field 1 contains “abc” AND field 2 contains “200”

thanks
