Are there any nosql database could do search(like lucene) on map/reduce

I'm using cloudant which I could use mapreduce to project view of data and also it could search document with lucene

But these 2 feature is separate and cannot be used together

Suppose I make a game with userdata like this

{
    name: ""
    items:[]        
}

Each user has item. Then I want to let user find all swords with quality +10. With cloudant I might project type and quality as key and use query key=["sword",10]

But it cannot make query more complex than that like lucene could do. To do lucene I need to normalize all items to be document and reference it with owner

I really wish I could do a lucene search on a key of data projection. I mean, instead of normalization, I could store nested document as I want and use map/reduce to project data inside document so I could search for items directly

PS. If that database has partial update by scripting and inherently has transaction update feature that would be the best

I'd suggest trying out elasticsearch.

Seems like your use case should be covered by the search api

If you need to do more complex analytics elasticsearch supports aggregations.
