Uwe, I don't have the answer to your main question, but will point you to the ngram set of tokenizers in Lucene's contrib/, in case you want to use that instead of maintaining your own bi-gram tokenizer.

We use lucene in our product since version 1.2. I have developed a new Bigramm stemmer and would like to get a suggestion how to implement the needed scorer for it. Using a Boolean query with a slope I get most of the time the correct documents. For example: The Bigramm split for "document" is do oc cu um me en nt If a user searches the misspelled "documnts" I use a Boolean query with a slope depending on the length of the search term. This works quite well , as do oc cu um mn nt ts gives 6 correct terms. But I want to implement in addition that terms which follow each other in the indexed doc in the same order get a higher score. In this case we have 5 terms in the correct order which should give to the doc a boost of 4 (relatively spoken). What type of query should I base the development of my scorer on?
