Fortunately this WSDL is rpc/encoded so SOAP::Lite converts the response SOAP document into reasonable perl structure.

As you found the result of doGoogleSearch call is a reference to a hash with keys ( "searchTime", "endIndex", "searchComments", "documentFiltering", "searchTips", "estimatedTotalResultsCount", "searchQuery", "startIndex", "resultElements", "directoryCategories", "estimateIsExact"). The hash can be analyzed the way you did. Actually the hash reference is an object - it is blessed into GoogleSearchResult package - but this package is empty, so there is no object api available.
