I've been using a trick in G+ search to find my comments like this.
https://plus.google.com/s/%22Julian%20Bond%22%20-inurl%3A106416716945076707395/posts
However I'm finding now that -inurl:my_profile_id isn't removing posts posted by me. I've tried also using -inurl:my_profile_short_url but that also fails. inurl: without the - never used to work as a keyword. -inurl: seems to do something, just not what you'd expect. So is it now broken?
Is there an accurate current list of the search keywords anywhere?
The real problem here is the lack of a function in G+ to list my comments. Just one of many inexplicably missing functions.
