Hi Erik,
My requirement to index the documents of particular organization to specific
shard. Also I have made changes in core.properties as menions below.
Model Collection:
name=model
shard=shard1
collection=model
router.name=implicit
router.field=core
shards=shard1,shard2
Workset Collection:
name=workset
shard=shard1
collection=workset
router.name=implicit
router.field=core
shards=shard1,shard2
here I have also created new field 'core' which value is any shard where I need
to send documents and on retrieval use '_route_' parameter with mentioning the
particular shard. But issue facing still my clusterstate.json showing the
"router":{"name":"compositeId"} is it means my settings not impacted? or its
default.
Please do needful.
Regards,

You cannot just make configuration changes, whether you use implicit or
compositeId is defined when you _create_ the collection and cannot be changed
later.
You need to create a new collection and specify router.name=implicit when you
create it. Then you can route documents as you desire.
I would caution against this though. If you use implicit routing _you_ have to
insure balancing. For instance, you could have 10,000,000 documents for "Org1"
and 15 for "Org2", resulting in hugely unbalanced shards.
Implicit routing is particularly useful for time-series indexing, where you,
say, index a day's worth of documents to each shard. It may be appropriate in
your case, but so far you haven't told us _why_ you think routing docs to
particular shards is desirable.
Best,
Erick
