If you have specific areas of interest that are unpopular enough your local yacy instance can index those [say] 100 or 10 000 websites and the results will blow you away. Google is still useful of course but its a joke by comparison.
Say for laughs you are only interested in yourself. You put every page by you and about you in the crawler. It will obviously render fantastic results. Using google you would have to start every query with your full name OR user names, whatever you type behind it doesn't even matter, it wont return pages with all keywords. With yacy you just type the query and it will return EVERYTHING. To compare the 2 would be to compare useless with perfection.
