Is there a way to sort posts by rating like on other r34 sites?
example: order=score_desc

do you mean like this?
rule34.xxx/index.php?page...st&tags=score%3a%3E10

or like this?
rule34.xxx/index.php?page...st&tags=rating%3asafe

no i think he means like "sort:score:desc"

however last time i tried this i think it was sorting lexically instead of numerically
so 9 would come before 81, for example

thx for the replies!

yeah it actually looks like "sort:score:desc" is pretty much totally broken

but as mrcold said, you can still use "score:>N" for some purposes

if you want to find the highest rated images in the gallery, use "score:>500"

it doesn't seem to work with with negative numbers; you can't search "score:<-50" to get the lowest rated pictures, for example
