Scan is the more appropriate method:
irb(main):001:0> s = “Hi this is for test”
=> “Hi this is for test”
irb(main):002:0> s.scan(“Hi”)
=> [“Hi”] # creates an array if the required word matches

Otherwise you can use regexp with a conditional:
irb(main):003:0> if s=~ /Hi/
irb(main):004:1> puts “found”
irb(main):005:1> end
found

include? is another solution:
irb(main):007:0> s.include?(“Hi”)
=> true

Wouss is correct that a simple search would have shown you the answer.
Still, I ask questions here and it is my turn to help with an answer.

With something like this:
“Hi this is for test”.index(‘Hi’)

you get a nil if there is no match and the starting point of the string
found if there is one.

e.g.

puts ‘string found’ unless “Hi this is for test”.index(‘Hi’) == nil
