Java regexes operate on unicode strings, so ".' matches any *character*
There is no regex syntax to match an any "byte" so a regex based approach
is never going to be viable.
You're best bet is to check the byte count when indexing -- but even then
you'd need some custom code since things like
FieldLengthUpdateProcessorFactory are well behaved and count the
*characters* of the unicode strings.
If you absolutely can't reindex, then you'd need a custom QParser that
produced a custom Query object that iterated over the TermEnum looking at
the buffers and counting the bytes in each term -- matching each doc
assocaited with those terms.
