The parentheses are redundant. Perhaps it is an Aquamacs issue. With
GnuEmacs 24 on Linux, the following search works fine:

C-c / / TODO\|STARTED

That said, for this use, a TODO keyword search will be quicker and more
accurate, as the regexp search above will match "todo" or "started"
anywhere in the buffer. Here's the todo search:

C-c / T TODO|STARTED

Best,
