Looks like I was using the wrong field when searching (tokenized instead of untokenized) and this approach actually worked. Sorry for the confusion.

In my plugin I've subclassed the SolrQueryParser and overridden the getFieldQuery(...) method so that I can handle queries that contain spaces and wildcards. I naively tried to construct a WildcardQuery object from the query text but that didn't seem to work. What sort of Query object(s) should I be using here? (Note: the field I'm working with is an untokenized field).

Then you won't need to use wildcards at all, but you'll have a larger index. 2) may be added to Lucene in the near future, actually, I saw a related JIRA issue. But in the mean time, yes, you coul dimplement it via a custom QParserPlugin.
