Sorry, yes my mistake - foo, FOO and Foo all return the same results. 
I must have made an error in my earlier experiment.

Uhh, I guess I am confused because the search *is* case insensitive.   
From RFC 1176:

       In all search criteria which use strings, a message matches the

       criteria if the string is a *case-independent* substring of that

       field.



For me, searching for 'foo' and 'FOO' returns the same subset of messages.

We probably can't, since searching is done on the server side. Unless 
there is some parameter we can provide to change this behaviour. 
Michael?

Having looked at this further, you are correct, however the search 
seems to be case sensitive, which does not seem logical to me - 
perhaps it should be made case insensitive?



Nick.

There are no wildcards AFAIK, searches are always substring searches 
which is the most intuitive for users anyway. So I don't see a need 
for any further explanations in the online help.

The help page on message search does not explain how to use wildcards 
in search, for example, whether I can search for all messages 
containing the text "123456", and if so, how to specify the wildcards, 
e.g. "*123456*" or "%123456%" etc.
