QuoteAlso, which lines would i need to add to the python script so the results with a rating lower then a set value, say three stars, wouldn't be added to the results?

open up the python script.

and add

searchfor = searchfor+ ' and Rating>"60"'

just before the line
searchstring = searchterm+' like '+searchfor+' order by random() limit '+maxresults


edit: actually, I'm not 100% sure about this because >"60" doesn't really make sense... I'd have to experiment a bit.

here's the volume
