textIndexVersion:2 indexes observe subdocument language annotations (and correctly index nested arrays, if not directly nested). The text search matcher needs to invoke the correct language stemmer on text contained in subdocuments (and examine fields in nested arrays for determining a match), but doesn't.
Reproduce with:
> db.foo.ensureIndex({"a.b":"text"})
> db.foo.insert({a:[{b:["example content"]}]}) // note indexed nested arrays
Insert WriteResult({ "ok" : 1, "n" : 1 })
> db.foo.find({$text:{$search:"example content"}}) // correct
{ "_id" : ObjectId("52aa57a0ae39c4212eb00625"), "a" : [ { "b" : [ "example content" ] } ] }
> db.foo.find({$text:{$search:"example -content"}}) // incorrect: should return empty result set
{ "_id" : ObjectId("52aa57a0ae39c4212eb00625"), "a" : [ { "b" : [ "example content" ] } ] }
> db.foo.find({$text:{$search:"example \"content\""}}) // incorrect: should not return empty result set
