Feature request: URL whitelist with an option to import web browser favorites (domains)

[Daevu]

The goal would be to give the user an option to only display search results (and store/distribute index data) of websites that were found helpful in the past. Of course, this would basically create a filter bubble, but then, nobody would be forced to use this feature, and you could still run a second (unfiltered) yacy instance on the side.

However, something similar, to a certain extend, can already be achieved with a search query which includes the desired websites:

yacy inurl:(whonix.org|searchlab.eu|github.com)

But, the longer the search query, the slower the search, and there's probably a maximum number of characters allowed in a query. Moreover, in the default P2P mode, index data of other websites are still received and distributed in the background, slowing down the search and eating up computer resources.

I'm also wondering, if there's some clever regex trick, which let's you inverse a blacklist entry - basically turning it into a whitelist entry.

I have figured it out. If you enter the following string into your yacy blacklist, it will transform it into a whitelist, and from now on only results from whonix.org, searchlab.eu and github.com (incl. subdomains) will show up in your search results.

(?!(.*\.)?whonix\.org|(.*\.)?searchlab\.eu|(.*\.)?github\.com).*/.*

Leave out the (.*\.)? if you only want to allow specific subdomains or no subdomains at all.

Edit 1: previous rules didn't work properly
Edit 2: dots need to be escaped too
