Before initiating a search, state the extension that interests you by clicking the "view preference" button.
Search a domain name by subject: simply enter a word of your choice (one at a time) in the DomRaider search bar, then validate. Your search will show all the domain names and anchor tags containing that word.
Search a domain name using metrics: Go to the "view preference" option, select the extensions that interest you as well as the metric(s), then validate. Now select the "all domains" option. You can sort these using a preferred metric but using the "sort by" button.
