Multiple routing field in elasticsearch

I am a newbie to elasticsearch. i need a clarification. i can understand how routing works, but I have a question.

Can i create routing for an document with multiple field. if yes, can i search the data using single routing value. Can any on provide any example about it.

Imagine I have 5 fields: [username,id,age,dept,salary]. Now i need to create a routing value for this document. Can I do so using the username and id field?

Thanks in advance.

In answer to your question: no, you can't automatically use multiple fields for a routing value when indexing a document. You can choose one and only one field, and that field must contain a single value.

However, you could manually concatenate the username and id field and pass it in the indexing request:

PUT /index/type/id?routing=username_id
{ body }

That said, routing is a feature for more advanced users. It is very useful but does make life more complicated. You say that you're a newbie, so I'd suggest not playing with routing just yet. That can follow when you're running a 50 node cluster.
