bq. Karl, did you ever proceed on this patch? I'm interested in adding 
autosuggest to Solr.

I used this patch for a few things a couple of years ago. If I recall 
everything right I ended up using the bootstrapped apriori corpus of LUCENE-626 
as training data the last time. Made the corpus rather small, speedy and still 
relevant for most users.

But the major caveat is that this patch is a trie and is thus a "precise 
forward only" thing. So that might not fit all use cases. It might be easier to 
get things going using an index with ngrams of untokenized user queries (i.e. 
including whitespace) or subject-like fields. 

But I really prefere user queries as using only the last n queries will make it 
sensitive to trends. That will however require quite a bit of data to work 
well. A lot as in hundreds of thousands of user queries, according to my 
experience.

Not sure if this was an answer to your question.. : )

(from a mail i just posted to java-user)

There is a memoryleak in the trie at optimize() that has been fixed locally. 
Might be available in LUCENE-626 too. 

I'll repackage and post it up as soon I get time.
