I'm learning to use Postgresql's bitwise operator's as I'm interested
in building super fast search's based on user selections in web forms.

So far so good but I have just lost it a little so I thought I'd post.
Please growl at me if I'm asking on the wrong list :-)

I understand this:

SELECT 111 & 11 = 11

but not this

SELECT 1111 & 111 = 71

I was expecting the second example to be 

SELECT 1111 & 111 = 111   </pre></blockquote><pre wrap="">
In the above examples the numbers are decimal values.

Maybe you wanted to do something like the following:

area=> select b'1111' & b'0111';?column?
----------0111
(1 row)
