I think this is possible, at the Lucene level. You want a mix of PrefixQuery and SpanFirstQuery (hmm we don't have a SpanLastQuery...).
I believe you can do this by creating a PrefixQuery, and then customizing the rewrite method to create a BQ (SHOULD clauses) of SpanFirstQuery, instead of TermQuery that's used by default. Alternatively, you could enum all matching terms and then build the BQ yourself... but you'll have to be careful when too many terms match the prefix.
