What do you want actual user queries to look like? I mean, having to explicitly write asterisks after every term is a real pain.
Indexing ngrams has the advantage that phrase queries and edismax phrase boosting work automatically. Phrases don't work with explicit wildcard queries. The only real downside to ngrams is that they explode the size of the index. But memory is supposed to be cheap these days. I mean, compare the cost of the extra RAM (to keep the full index in memory) to the cost to users of tehir productivity constructing queries and having expensive staff to help them figure out why various queries don't work as expected.
