try this one, it's case sensitive:

procedure TForm1.Button1Click(Sender: TObject);
var FText: string;
size: integer;
Buffer, FindBuf: PChar;
A: array[0..255] of char;
begin
  if InputQuery('Find Text', 'Enter text to find:', FText) then
  with memo1 do begin
    setfocus;
    size:=gettextlen+1;
    GetMem(Buffer,Size);
    GetTextBuf(Buffer,Size);
    FindBuf:=StrPos(Buffer,strPCopy(A,FText));
    if FindBuf<>nil then
    begin
      selstart:=Size-StrLen(FindBuf)-1;
      sellength:=length(FText);
    end
    else
      showmessage('not found');
    FreeMem(Buffer,Size);
  end;
end;

This is a good code, but maybe I should learn to write exactly what I want to do. I want to search for 2 or more different words in a memo and in case not sensitive.

1. to make the search in case not sensitive write:
   FindBuf:=StrPos(strupper(Buffer),strupper(strPCopy(A,FText)));
   instead of
   FindBuf:=StrPos(Buffer,strPCopy(A,FText));
2. to find 2 words or more expand this basic procedure for your       own needs, say run this procedure a number of times as the       number of words you need to find.
