wever I don't fully understand what do you mean by "iterate over your
query". I would like a conceptual answer how is this done with
Lucene, not a technical one..
Your query is a tree, with BooleanQuery as branch and other query as
leaf. If you wont to transforma query in "tolerant query", you have to
change Term query (the leaf), with a "OR" branch with variant term as
leaf.
To find variant of a term, you have to used a list of your Term and
apply a filter to its to group them. Common filter for that are
stemming, ngram+levenstein distance, phonetic ...

OK, now it's more clear.. my final question is when is this filter
information incorporated.. at index time or at search time? i.e. I want
to know whether the levenshtein distance is computed at query time or
this information is precomputed in the index?
