I'm probably closer to understanding, but can't figure out how to find 
packages that have a particular string in their message.

For example:

% pkg query --evaluate '%m = me@forkbomb9.ch' %o
net-mgmt/netdata
% pkg query %M netdata
On install:
Quick start for local-only use:

1. sysrc netdata_enable="YES"
2. service netdata start
3. Go to http://localhost:19999/
4. <Optional> Connect to Netdata Cloud using the netdata-claim.sh script:
https://learn.netdata.cloud/docs/agent/claim#claiming-script

% pkg query --evaluate '%M ~ netdata' %o
%

Where the third command did not find a package with the phrase 'netdata' 
in its message, what am I doing wrong?
