How to escape both single quotes and exclamation marks in bash

I have a long command and I just want to use alias to shorten it. But the command contains single quotes and exclamation marks. The origin command is ldapsearch -x -H ... -w 'abc!123'. I tried alias search='ldapsearch -x -H ... -w \'abc!123\'' or alias search="ldapsearch -x -H ... -w 'abc!123'" and so on. But none of them works for me.
