More downloads said of the tab then there are.
 

When I search for things, it says on the search tab the number of downloads there are, but usually it only shows a lot less on the acutal page.

For instance, it says

[x] vib ribbon (156)

but on the page, it only shows about 5 or 6 downloads. Why is that, and how do I make it so I can see all of the downloads?

It is the number of locations it has found, not the number of files. :)

i.e

SONG ARTIST (13)
- (3) song name
- (6) another song name
- (2) another song name
- another song name
- another song name

The results with the bracket'ed number show that that exact file has been found in however many different hosts. If you know what i mean. :)

Here is a thousand words
