Hi Konstantinos

 I am not able to reproduce the error. I can use different
search queries of different length, etc.

  The error is coming from libcurl and, if I have gotten things the
right way around, it basically means that the write handler callback
didn't handle the entire collection of text it was given.
Can you

curlPerform(url="http://soap.search.msn.com/webservices.asmx?wsdl",
             httpheader=c(Accept="text/xml", Accept="multipart/*",
                          'Content-Type' = "text/xml; charset=utf-8"),
             postfields=body,
             writefunction = function(txt) { print(txt) ; nchar(txt)},
             verbose = FALSE
 	    )


and verify that the we do get the point where we are processing the
return from the server (and not failing in writing our request to the
server).

If the error is in handling the response from the server, then it may
be that we have to look at the string encodings, etc.
