IF i have a string a ="a" and a string b= "ab" can i use
if a in b then
something
end

No - the in keyword is only used for looping over things (for k, v in pairs(some_table) do ... end).

If you want to check if one string is in another, you can use Lua patterns and string.find:

local a = "a"
local b = "ab"
if b:find(a, 1, true) then
  -- something
end
