Problem:
$exists appears to match arrays in a dotted expression differently between versions.
Reproduce:
db.q.drop()
db.q.insert({ "a" : [ { "0" : { "2" : { "b" : "To the man who only has a hammer, everything he encounters begins to look like a nail." } } } ] })
db.q.insert({ "a" : [ { "0" : { "2" : { "b" : 99 } } } ] })
db.q.insert({ "a" : [ { "0" : { "2" : 42 } } ] })
db.q.insert({ "a" : { "0" : { "x" : 42 } } })
db.q.find( { "a.0.2" : { $exists : 0 } } )
2.4.5 returns
{ "_id" : ObjectId("527068948a43120c67c8c621"), "a" : [ { "0" : { "2" : { "b" : "To the man who only has a hammer, everything he encounters begins to look like a nail." } } } ] }
{ "_id" : ObjectId("527068948a43120c67c8c622"), "a" : [ { "0" : { "2" : { "b" : 99 } } } ] }
{ "_id" : ObjectId("527068948a43120c67c8c623"), "a" : [ { "0" : { "2" : 42 } } ] }
{ "_id" : ObjectId("527068948a43120c67c8c624"), "a" : { "0" : { "x" : 42 } } }
2.5.4-Pre returns
{ "_id" : ObjectId("527068b76ca3a8357d0fe436"), "a" : { "0" : { "x" : 42 } } }
