I am using this code in my website to show Google search results for my website :
<!-- Search block -->
<div class="searchBox">
<form method="get" action="http://www.google.com/search">
<input type="text" name="query" class="searchField" />
<input type="hidden" name="sitesearch" value="my_website.com">
<input type="submit" value="" class="searchSubmit">
</form>
</div>
I like that simple code and i do not prefer to use Google Custom Search, but is there a way to show the output of this search embedded in a page i specify ?
