Filtering the Content By Query Web Part on a Yes/No Field

Here is a great post on something that I know I'll forget and that isn't that intuitive.  When filtering on a Yes/No column, I kept trying to input the value of "True" or "Yes" for the filter value.  The technique is as described in this post:!1CC1EDB3DAA9B8AA!463.entry

Which is to use the strictest boolean implementation of the column "1" or "0".
