I was lucky to contribute an excellent solution: http://issues.apache.org/jira/browse/LUCENE-2230
Even 2nd edition of Lucene in Action advocates to use fuzzy search only in exceptional cases. Another solution would be 2-step indexing (it may work for many use cases), but it is not "spellchecker" 1. Create a regular index 2. Create a dictionary of terms 3. For each term, find nearest terms (for instance, stick with distance=2) 4. Use "copyField" in SOLR, or smth similar to synonym dictionary; or, for instance, generate specific Query Parser... 5. Of course, custom request handler and etc. It may work well (but only if query contains term from dictionary; it can't work as a spellchecker) Combination 2 algos can boost performance extremely...
