An easy way of narrowing down 'Hits' in any search is, if you know the 'Forum' the quote, picture, or word your looking for is in e.g 'Doctor, Medical & Old Remedies', 'Genealogy', 'General Discussion' etc... use the 'Search' at the top that section (It's on the thin line at the top of each page, under the 'Reply to thread' button and on the right hand side of the page.) rather than using the 'Main Search' right at the top of the whole page. This is also useful if you are looking for a post in a very big thread on the forum, as you will only get 'Hits' from that Forum, or Thread.
Hope everyone can understand what I have said....
