Omit feature on bing search

[Volcannon]

So normally if I search for something like Streets of Rage for example and I decide to put in -youtube, it should pull up a search with anything related to Streets of Rage except it would remove youtube from the list. Bing is STILL showing youtube despite me adding the omission.

I would like to know why the -youtube is not working and if there is an alternate solution for this problem you do not use - feature for your search engine.

Try using :SITE and NOT e.g. Streets of Rage NOT site:youtube.com

So what about single words then? How do I omit single words from my search result, cause the - next to the word is not working.

Just use NOT before the word

I tried and it still lists it in the search result.
