[R] Microsoft SOAP - Help!!

[Metaxab]

Hello,

I am trying to access Microsoft Live Search Using SOAP through R.
In R I am using the RCurl packages to make the calls.

I have the following situation that looks crazy and cannot figure out how to
solve it:

#SOAP Request
library(RCurl)

h = basicTextGatherer()

body='<?xml version="1.0" encoding="ISO-8859-15"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle=" http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd=" http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENC=" http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body><ns3849:Search xmlns:ns3849="http://tempuri.org">
<Request><AppID xsi:type="xsd:string">MY ID</AppID>
<Query xsi:type="xsd:string">"Cancer"</Query>
<CultureInfo xsi:type="xsd:string">en-US</CultureInfo>
<SafeSearch xsi:type="xsd:string">Off</SafeSearch>
<Flags xsi:type="xsd:string"></Flags>
<Location xsi:type="xsd:string"></Location>
<Requests><SourceRequest><Source xsi:type="xsd:string">Web</Source>
<Offset xsi:type="xsd:int">0</Offset>
<Count xsi:type="xsd:int">10</Count>
<ResultFields xsi:type="xsd:string">Title</ResultFields>
</SourceRequest></Requests></Request></ns3849:Search></SOAP-ENV:Body>
</SOAP-ENV:Envelope>'

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 = h$update,
            verbose = FALSE
	    )

##Put the responce in body.
body = h$value()
h$reset()

An now the crazy stuff. This code works well for some keywords but not for
all.

So for the Query:"Cancer" the code works fine, but for the Query: "Tiger" I
get the following error message: 
  Error in curlPerform(url =
"http://soap.search.msn.com/webservices.asmx?wsdl",  : 
  Failed writing body

I cannot figure that out. Please help!!!!

Thanks
