Search form code for vBTags?

[hurry]

Greetings. I have installed the vBTags mod from vb.org. But there is no support on that thread. So I am seeking help here for a simple requirement:

If I need to search for a tag xxxx for example, I have to enter the following url in my browser and it will display all posts with this tag xxxx:

http://www.mywebsite.com/tag.php?name=xxxx

I wanted to make a form or Search box for this where the user can manually enter the tag query they want to search for and tag word will get appended to the url http://www.mywebsite.com/tag.php?name= after the equal to sign and the url will load in the browser to display all the posts with this tag. How can do I do this? Please let me know the code. Any help will be most kindly appreciated with gratefulness.
