The aob of the ceaa script can specify the module search. Can the aob of lua not specify the module search?

no there's not a lua function that restricts it to a module, though you can use autoAssemble to build and assemble an AA script that registers a symbol and use aobscanmodule or aobscanregion in lua that way.

Code:

--[[ SETUP ]]--
function AOBScanAA(script, symbol)
  local success,disableInfo = autoAssemble(script)
  if not success then return nil, disableInfo end -- disableInfo is error message on failure
  local addr = getAddress(symbol)
  autoAssemble(script, disableInfo) -- disable script and unregister symbol
  return addr, 'success'
end

function AOBScanRegion(bytestr, start, stop)
  local script = ([[
  [ENABLE]
  aobscanregion(luaAOBScanRegionSymbol,%X,%X,%s)
  registersymbol(luaAOBScanRegionSymbol)
  [DISABLE]
  unregistersymbol(luaAOBScanRegionSymbol)
  ]]):format(getAddress(start), getAddress(stop), bytestr)
  return AOBScanAA(script, 'luaAOBScanRegionSymbol')
end

function AOBScanModule(bytestr, module)
  local script = ([[
  [ENABLE]
  aobscanmodule(luaAOBScanModuleSymbol,%s,%s)
  registersymbol(luaAOBScanModuleSymbol)
  [DISABLE]
  unregistersymbol(luaAOBScanModuleSymbol)
  ]]):format(module, bytestr)
  return AOBScanAA(script,'luaAOBScanModuleSymbol')
end

--[[ TESTING ]]--

-- Tutorial step 1 load
--local addr,msg = AOBScanRegion('8B 83 80040000', 0x00423000, 0x00424000)
local addr,msg = AOBScanModule('8B 83 80040000', process)

if addr then
  print(('0x%X'):format(addr))
else
  print(msg)
end


There's also the memscan object that has all the same options as the gui including read/write/executable flags

aobscan is just a memscan call in one line
memscan can be given a range to scan, so if you give it the range of a module it'll be the same
