Subject Re: How to routing document for send to particular shard range
Date Wed, 08 Nov 2017 07:05:37 GMT
Ketan,

If you know defined indexing architecture; isn't it better to use
"implicit" router by writing logic on your own end.

If the document is of "Org1", send the document with extra param*
"_route_:shard1"* and likewise.

Snippet from official doc:
https://lucene.apache.org/solr/guide/6_6/shards-and-indexing-data-in-solrcloud.html#ShardsandIndexingDatainSolrCloud-DocumentRouting
:

If you created the collection and defined the "implicit" router at the time
> of creation, you can additionally define a router.field parameter to use a
> field from each document to identify a shard where the document belongs. If
> the field specified is missing in the document, however, the document will
> be rejected. You could also use the _route_ parameter to name a specific
> shard.
