Mck SembWever commented on LUCENE-1380:
---------------------------------------
> separate out this feature to a new filter that modify the position increment.
As Chris explained in the list this approach would clobber all terms into one
big synonym group. There may be other terms in the query outside of the quotes
which should not be treated as synonyms to the shingles. And it was also
mentioned that there were known bugs when the first token had
positionIncrement=0 (or all tokens lay at position zero instead of at position
one).
i imagine that this rules out such a position increment TokenFilter.

> Make it possible for *all* words and shingles to be placed at the same
> position, that is for _all_ shingles (and unigrams if included) to be treated
> as synonyms of each other.
> Today the shingles generated are synonyms only to the first term in the
> shingle.
> For example the query "abcd efgh ijkl" results in:
> ("abcd" "abcd efgh" "abcd efgh ijkl") ("efgh" efgh ijkl") ("ijkl")
> where "abcd efgh" and "abcd efgh ijkl" are synonyms of "abcd", and "efgh
> ijkl" is a synonym of "efgh".
> There exists no way today to alter which token a particular shingle is a
> synonym for.
> This patch takes the first step in making it possible to make all shingles
> (and unigrams if included) synonyms of each other.
> See http://comments.gmane.org/gmane.comp.jakarta.lucene.user/34746 for
> mailing list thread.
