Thanks Erick. I went through the doc https://lucidworks.com/2015/05/12/rule-based-replica-assignment-solrcloud/ and it helped on how to use "host" tag. However can I use two values to same key.?
I can do host:!1.1.1.1 but can I do something like host:!1.1.1.1,!2.2.2.2 or host:!1.1.1.1,host:!2.2.2.2 I dont see it in the doc Thanks On Mon, Dec 11, 2017 at 9:46 PM, Erick Erickson <erickerick...@gmail.com> wrote: > Take a look at the collections API CREATE command, especially the > "createNodeSet".
