Hi
I have checked the src in
DistributedUpdateProcessor.doDeleteByQuery(DeleteUpdateCommand cmd) as[1]
According to the source code,it seems that ShardParams._ROUTE_ (_route_)
and the ShardParams.SHARD_KEYS(shard.keys)
would be used to find the right shard.
Compared to my last two posts,the shards is not the right properity to
identify the right shards that really need to delete the docs.
Am I right?
Does it need to add the processeing about the shards to unify the
process?

..omitted..
String route = params.get(ShardParams._ROUTE_);
if(route == null) route = params.get(ShardParams.SHARD_KEYS);//
deprecated . kept for backcompat
Collection<Slice> slices = coll.getRouter().getSearchSlices(route,
params, coll);
List<Node> leaders = new ArrayList<>(slices.size());
for (Slice slice : slices) {
..omitted..
cmdDistrib.distribDelete(cmd, leaders, outParams);

}
