make a sepcified search engine for a certain section

Hey I couldn't submit this to tutorials so I figured I place it here. Have fun with it.

Code:

<div class="search-box"><form method="get" id="forum-search" action="/search.forum"><fieldset><input class="inputbox search tiny" name="search_keywords" id="search_keywords" size="20" value="Search" onclick="if (this.value == 'Search') this.value = '';" onblur="if (this.value == '') this.value = 'Search';" type="text">&nbsp;<input class="button2" value="Search" type="submit"><input value="c3" name="search_where" type="hidden"></fieldset></form>

in this code in the end you see c3 change this into the forum number you want to specify the search engine for

example
this is the original link on which this search engine with the above code is specified.
http://achieve360portal.com/list-a-to-z-c3/
all threads will have a certain number behind the name you gave it.
I gave that section the name
list-a-to-z so the cs3 is the number which should be filled in. to make this new search engine either make a module in your portal or paste it in a html page and link to it.
thats all, really easy mod.

cheers max
