<FAST installed drive>:\FastESP\adminserver\webapps\help\pdfs\assets\pdf\ESP_Query_Language_Prameters_Guide.pdf has the following information which explains this a bit more:
Wildcard Expression A wildcard expression indicates a single term or phrase that includes one or more of the wildcard characters `*' and `?'. FAST Enterprise Search Platform supports wildcard search for individual string-type Fields, Scope Fields and Composite Fields. The capabilities are slightly different, as described below.
Tip: Wildcard queries will return a syntax error if the target is a composite field and this composite field is not configured for wildcard (wildcard="no").
