Hi friends,

   I need to search exact match from sentence .I want the expected
behavior should be like below by using ruby

···

=========================================================================
message = "The quick brown fox jumps over the lazy dog.”

Expected results :
              searchdata = “brown fox” should match
              searchdata = “brownfox” Donot match

       if message like message = "The quick @brown fox jumps. over the
lazy dog.”
              searchdata = “brown fox jumps” should match

if message like message = "The quick @@brown fox jumps.# over the
lazy dog.”
                             searchdata = “brown fox jumps” Doesnot
match

Can anyone help

With the last example why should "brown fox jumps" not match "The
quick @@brown fox jumps.# over the lazy dog."?

The substring "brown fox jumps" starts at position 12.

after word

The you could use a.index(b) to find at what position b starts as a
substring of a and use that to look backwards two characters and check
them if they are acceptable.

def is_match(a, b)
  pos = a.index(b)
  if pos == nil
    return false
  elsif pos < 2
    # we matched within the first 2 characters of the string
    # there is not enough room for special charaters
    return true
  elsif a[pos-2,2] == '@@'
    return false
  else
    return true
  end
end
