Karl Wettin commented on LUCENE-1380:
-------------------------------------
One could argue that what you should do rather than using this patch is to add
a TokenFilter that sets all positionIncrement to 0.
> 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.
> See http://comments.gmane.org/gmane.comp.jakarta.lucene.user/34746 for
