Yonik Seeley commented on SOLR-1553:
------------------------------------
I guess one of the main questions is if this should remain separate from
dismax, or if it should eventually replace dismax? If the latter, they could
either co-exist for some time and eventually replace, or remain uncommitted
before it can replace...
Incompatibilities off the top of my head:
- "pf" creates word bigrams for proximity boosting... we could perhaps change
this to "pf2" and add in support for the dismax-style pf
- fielded queries - dismax doesn't have them, and they may not be desired by
all clients
- full lucene syntax - same as above - may not be desired by all clients
I think the other incompatibilities would mostly fall in the category of bugs,
or things that weren't well specified or well behaved anyway (e.g. I don't
really see a downside to allowing nested pure negative queries to work)
