Shea Houdmann runs SeekFind, a Colorado Springs-based Christian search engine that only returns results from websites that are consistent with the Bible. He says SeekFind is designed "to promote what we believe to be biblical truth" and excludes sites that don't meet that standard.
Houdmann says a search on his site would not turn up pornography. If you search “gay marriage,” you would get results that argue against gay marriage. And if you type in “Democratic Party,” your first search result is a site on Marxism.
Addendum: I couldn't get the Christian search engine to work at all; the site blames heavy traffic [I tried again; googling my name gets you to Tyler Perry. If you google "economics", "Islamic economics" pops up before "Christian economics" and "postmodern economics" comes before both]. The Halal site brought up more or less normal results both for my name and for "economics," although page one for the latter had some squirrely (non-Muslim) results, such as Hunter College. I don't appear in Jewogle at all, but an economics query will bring you to a list of Nobel Laureates.
