I have an easy way (I think! ) of searching for all pages from a specific website, containing a word / several words.

Taking the (dare I say it ) fridge as an example:

1. Go to google advanced search:
http://www.google.co.uk/advanced_search?hl=en

2. Type in the box about halfway down called "Search within a site or domain:" the website where you think you saw it (example):
http://forums.mirror.co.uk

3. In the box at the top, type in "fridge"

4. Hit Search

You should get the results (everything fromthe MF containing the word fridge).
In the google search page it should show as:
fridge site:http://forums.mirror.co.uk
(fridge = search term), (space), (site = website you want to search inc subpages)
