I want search engine to find sites containing the most the rare propper nouns I search for

I want to all sites that do a certain thing and I think people all over the internet make small lists containing some of these sites together. For example I want to make a list of all Quantified Self . I first search for zenobase and exist.io and find sites mentioning gyroscope and quantimodo. I add those to the search string and receive just Quantimodo site. If I add OR between each of the 4 proper nouns (zenobase OR exist.io OR gyroscope OR quantimodo) I get each word mentioned once instead of whatever sites mention most of these words. I need google or any search engine to find sites with the most of these items mentioned.
