Blogger search widget not working?

Here’s the solution:

Create a Blogger search widget

Login to your Blogger account and head over to Layout > Page Elements. Click on Add a Gadget at the bottom of the page and select HTML/Javascript.
In the Title field, enter Search or something similar. In Content, paste the following code:

<form action="search" name="input" method="get">
<input value="Search" name="q" size="20" type="text"/>
<input value="Go!" type="submit"/>
</form>

Hit Save and position the widget in the desired location. That’s it!
