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?
