How to search Google Plus posts and profiles

It has been one of my concern about Google+.  Why the hell Google has a product without a nice search function?  Isn’t Google a search engine company?

I found a way to overcome this:

With the following trick you can add the search function back to Google+ in Chrome.  Firstly, go to settings (here is the shortcut), and add the following entries:

Search Streams (Posts)

• Column 1: G+ Posts
• Column 2: gpost
• Column 3: {google:baseURL}search?q=site:plus.google.com inurl:posts/* %s

Search Profiles

• Column 1: G+ Profiles
• Column 2: gprofile
• Column 3: {google:baseURL}search?q=%s&tbs=prfl:e

After this is done, you can search in the Chrome address bar (omnibox) by typing “gpost” or “gprofile”, then press [tab] key and enter the keyword to search.

This is the search result of profile search:
