Tip Jar Multi-site Search with DuckDuckGo
To search the content of more than one site at time, DuckDuckGo provides the site operator which can contain more than one domain. To search both Macdrifter and Hobosigns I created this Workflow for iOS.
Prepending a search phrase with “site:macdrifter.com OR site:hobosigns.macdrifter.com” does the trick with a DDG search. Sites can even be across different TLDs. So, if you want to search 5 or 6 sites at once, consider a canned DDG cross site search.
