This Is How I Remove Tumblr Built-in Search Engine.

Keep adding tumblr built-in search engine on your tumblr blog is useless. Just like blogspot built-in SE, it was designed only display result if visitor type the right tagged words. I'm not sure if there are themes that show keywords as result. I find it rarely. So, in that case, you need to remove it and replace with Google Custom Search Engine.As you can see on my tumblr blog, i use Google CSE
