Michael Semb Wever commented on LUCENE-1380:
--------------------------------------------
Ok. So there's no way to do it through configuration only.
Would a patch with such a TokenFilter be useful for anybody else other than
ShingleFilter users? Again i'm a newbie here but i suspect there's no other
filter (yet) which works _across_ the tokens (and hence breaks down the
importance of positionIncrement) within a query in the way ShingleFilter does.
for example from the mailing list from steve:
> On the other hand, I'm not sure how useful position information is for
> shingles in the general case: they already have relative position info
> embedded within them. And how likely is it that one would want to perform a
> phrase/span query over shingles? Pretty unlikely, ...
> Patch for ShingleFilter.enablePositions

> Make it possible for *all* words and shingles to be placed at the same
> position.
> Default is to place each shingle at the same position as the unigram (or
> first shingle if outputUnigrams=false). That is, each coterminal token has
> positionIncrement=1 and every other token a positionIncrement=0.
> This leads to a MultiPhraseQuery where at least one word/shingle must be
> matched from each word/token. This is not always desired.
