Autosuggest is something that would be very useful to build into Solr as many search projects require it.
I'd recommend indexing relevant terms/phrases into a Ternary Search Tree which is compact and performant. Using a wildcard query will likely not be as fast as a Ternary Tree, and I'm not sure how phrases would be handled? http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/analysi It would be good to separate out the TernaryTree from analysis/compound and into Lucene core, or into it's own contrib. Also see http://issues.apache.org/jira/browse/LUCENE-625 which improves relevancy using click through rates. I'll open an issue in Solr to get this one going.
