Mck SembWever updated LUCENE-1380:
----------------------------------
Attachment: LUCENE-1380-PositionFilter.patch
> If you really want to do this change is this layer I suggest that you
> seperate out this feature to a new filter that modify
> the position increment.
Attaching alternative patch as suggested for PositionFilter and its test.
The first token always maintains its original positionIncrement, but subsequent
tokens in the TokenStream has their positionIncrement set to match the value of
PositionFilter.positionIncrement
I still fail to understand why Karl and Steve would rather see this logic in
the QueryParser. The best explanation so far was from Steve:
> IMO, the correct layer to solve this is in Solr's QParser -
> I think there should be a way to tell the parser not to parse, but rather to
> send the whole query to be analyzed.
but i wouldn't be surprised if this goes against the grain of how Solr works.

> 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.
