I have second thoughts about this engine, it's not good as I initially taught, it's *****in shit in fact.
A good litmus test for a DN search engine in putting in "hidden answers" as a query and see what happens. Well no matter how many times I try the only result I get is "***** ***** lesbian mia loli*****". Put in "hidden wiki" and likewise it will spew out some shit ***** link. This is a spoof honey-pot crap engine.
