This is the way those "boards" work to optimize huge requests. You could kill a server by doing a broad text search in a huge database.
Refine your research, choose carefully your keywords and select your tags and/or your categories in the advanced research. If you're actually "searching" something, if you're on page 5, you're already too far and your research terms are not precise enough.
And if you go beyond page 5, it just mean you're browsing. You should then use the categories themselves to browse through content.
