If you want to search for something such as a certain blog post within a specific site, this is a good way to find what you are looking for 

I use google search myself.  in the search box type what it is your looking for. example below
I am going to search for the blog titled: if they come to take your guns, here on 12160 from google

inside the search box I would type if they come to take your guns:www.12160.info

and all my results will be from 12160.info only. in order for this to work, just use the : after what you are searching for then add the site after that. no spaces between what you typed you are looking for and the :

Hope this helps out some in finding certain blogs and post. I use it alot because I can never seem to find what I'm looking for lol.

Also, you don't have to type the complete title to a blog or discussion, it will find everything starting with whatever you type. like if I didn't know the complete title to the above blog post I just searched. I could just type the following:   inside google search box I could type "if they come":www.12160.info and it would find every post, discussion etc with the "if they come" in it..
