I have not finished reading the document, but ASAIU, I think Lucene is still missing a PrefixSpanQuery (not hard at all I think) to implement correctly the main feature presented here. The exemple of the search "ontol sem" should be a near span query of two prefix span queries. Or maybe a PrefixPhraseQuery ? I haven't looked enought close to it to know what are the differences between the two.
