I'm not sure what you're going to gain from a regex if it's a specific
string and not a pattern.

irb(main):001:0> a = "Hello World"
=> "Hello World"
irb(main):002:0> !(a.include? 'Hello')
=> false
irb(main):003:0>

It seems you'd want to wrap that into a method to make the intent a little
more obvious

irb(main):011:0> def should_filter?(source, word)
irb(main):012:1> source.include? word
irb(main):013:1> end
=> nil
irb(main):014:0> should_filter?(a, 'Hello')

Just a thought.

to make the regex work as in your example though, you'd do this:
irb(main):021:0> !(a =~ /hello/i)
=> false

(case insensitive matching)
