Advanced searching a website, what software?

Hi everyone

I want to search discogs.com to find the releases (music) with best rating. Discogs search engine doesn't let users do this so I was using google:

"4.7/5" site:discogs.com rating -"No ratings yet" -"(1 vote)" -"(2 votes)" -"(3 votes)" -"(4 votes)" -"(5 votes)" -"(6 votes)" -"(7 votes)" -"(8 votes)" -"(9 votes)" -"(10 votes)" -"(11 votes)" -"(12 votes)" -"(13 votes)" -"(14 votes)" -"(15 votes)" -"(16 votes)" -"(17 votes)" -"(18 votes)" -"(19 votes)"

If you search that in google you get the idea

But google limits results to 1000

What can I do? Is there any good and free search software that let me do this?

Thanks!

 

I use to use this all the time:
