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
