progresses.behavior.name が "Mur (1)" に等しい配列ノードを削除しようとしていますが、このクエリを試しましたが、機能しません。

db.users.update({},{$pull : { "progresses" : { "behavior" : { "name" : "Mur (1)" }}}});
db.users.update({}, { $pull : {"progresses.behavior.name" : "Mur (1)"} }, false, true );

これはうまくいきました：

db.users.update({"progresses.behavior.name" : "Mur (1)"}, { $pull :  {"progresses" : { "behavior.name" : "Mur (1)"} } }, false, true );
