LUCENE-625 is very interesting, but not sure about the scalability. "Begin completion only with 3 letters or more" is reasonable for special cases, but not ideal. What I wanted to implement is a pretty general software. WildcardTermEnum seems closest to what I planned to search on existing Lucene index, possibly pretty large. I can use it to list, say top 10 matching terms, and I can use another search to find all matching docs. This is actually 2 searches.

You can get the information pretty quickly by using a WildcardTermEnum (NOT query). Especially if you terminate after some number of characters....
