It depends on when. TAU spans millenia. So does Alcor. Google…I’m not prepared to offer even an AU prediction on that.
If it’s way early on, you wouldn’t get many perfect matches before Google started returning things like “dream” on its own or stuff about the star or cyro companies with that name. Maybe there would be sites or blogs by people with a budding interest in the newly-discovered realm of demon summoning, listing known/discovered demons by names and titles. Lots of misinformation of course, and blatantly contradictory stuff. Maybe a news article or two if something really big happened and it was attributed to him, even tentatively.
Go further, and you’ll have more demon enthusiast blogs and lists and first person accounts which may or may not be true. Possibly some memes, depending on what the collective consciousness of social media has grabbed onto in the meantime. More reports. Some PSA styled stuff about NOT summoning demons, especially these, and other posts by various individuals contradicting it with or without evidence.
Get to and beyond the publishing and initial craze over Twin Souls, and good luck finding hits not related to that.
And on and on the rabbit hole goes, honestly. Fictional media, factually-styled stuff from various sources, memes and jokes and random chatter, occasional appearances of the name being used as a swear in some capacity, news reports, demonology research and publications, fanblogs, probably a thousand people online at any given time claiming to be the actual Dreambender (or just roleplaying)…
