I tried to search for
on Twitter, which is for Pokemon Go, but the user with the name "Shadow Onyx" kept on showing up (I need to sort by "latest"), so to use advanced search, I used
Shadow Onyx not @Darkeclipse19
because the user id of the user "Shadow Onyx" is @Darkeclipse19
But it can't find anything. To double check my search words, I also used
onyx not @Darkeclipse19
which should return all "onyx" posts excluding that user, but again it returned nothing, which is strange. So I tried to search using "onyx" and it showed many results not from that user.
So what should I use to get result for Pokemon's Shadow Onyx but not the user "Shadow Onyx"?
