map (associative array) loses values?

Just a note. I noticed in that code that in operator= I don't have a return
statement. I looked in my own code where I'm doing this same thing and also
don't have a return statement. I don't know if that's a compiler flaw not
catching it, or the standard allows it. I think, however, that
SearchText& opeator=( SearchText const& ) { return this; }
would be more correct, even though it will never be called.

You don't even have to define them
