This may be of help
Go to Google advanced search and in the
domain field enter
http://www.model-engineer.co.uk/forums
And then enter the word you are looking
for.
I entered Rust, and as David says, the
list can be long, in this case at least 100 forum entries
I then tried EW Lathe and was given 10.
So if you are looking for something not
that common you may find this useful.
If you look at Google’s Cached pages,
rather that the forum page direct, the word will even be highlighted.
Of course, if the item being searched
is very recent Google may not yet have found it.
On my PC the Advanced search facility
only becomes available after first doing a web wide search, but that
can be ignored.
I use this method to search my MEW
index on the web that runs to about 100 pages. I again searched for
EW lathe and it came up once in the lathe reviews pages.
The index is at
