Including Google Search box on my website

I have added a google search box on my website, code as follows:

<form method="get" action="http://www.google.com/search">

<input type="text" name="q" size="31"
maxlength="255" value="" />
<input type="submit" value="Google Search" />
<input type="radio" name="sitesearch" value="" />
The Web
<input type="radio" name="sitesearch"
value="mywebsite.com" checked /> Ask Dave Taylor<br />

</form>

However, Google fails to search anything in my website.

Similarly, If I make "sitesearch=bbc.com", again, google does not find any result.

But If I change the sitesearch variable to askdavetaylor.com, the search works fine.

So the question is, why doesn't google search box work for every website / domain??????

regards

it wont find bbc.com, cos there is no bbc.com - try it...it just sends you to bbc.co.uk

and it wont find your site, cos google hasnt indexed it, so doesnt know it exists.

so how do i include my site in the google index?????????????/

build it and they will come!

lol, seriously though, noone knows exactly how google works - kinda secretive, but one thing which is pretty sure is that it "spiders" the web. Basically, it takes a site which it already has been to, and follows every single hyperlink from it. Then it follows each hyperlink from there, and so on, so if no site links to yours, then you have no chance whatsoever of being found. In essence, whack your site in your sig here (and as many places as poss) and they will find you eventually.

Google for "how google works" and there's loads of tips to make google like your site

right, so there is no such index as a 'google index'

well there is - on the google servers, but there is no reliable way of getting onto it...its better to just get people to link to you

Just enter your url on this page and within a week Google wil start crawling and indexing your site.

I've did this with a blog of mine and after no more than a couple of days it started showing up in Google Search.
A lot of 1st page results too.

edit:
It says on the page that they don't add every url submitted there,but I did this with a couple of testblogs that had virtually nothing on them except for a "blablabla...this is just a test..."mesage on it,and ithey still got added.
