Zachary and David thanks a lot!

It looks like alias is my option!!

Let me try it.. I might need some help with creating an alias in Java API.
Anyone got few lines of code to create an alias, swap the index, how to
change the search call to use an alias?

Here is my code to perform search.

SearchRequestBuilder searchBuilder =
client.prepareSearch("supplier").setTypes(supplierCode);
QueryBuilder qb = QueryBuilders.wildcardQuery("name", nameLike);

Thanks

I don't think you can rename a Type.

But, you can create a new index with the same Type name and use alias to
add the new index in addition of the older one and then remove the old type.

Does it help?

I have my index created with multiple types, each type represents
different different sets of data, having about 200K documents per type.
Number of types per index could go up to 50 at the max.. At present I have
5 types in my index.

To make sure that my index is up to date, I have a thread that runs once
in a day to collect any missing documents, deleted documents from the
database and update the index, so that I make sure 100% of the documents
are available to search. To perform this task, I am rebuilding the type
from scratch - by deleting the mapping for the given type and re-creating
the mapping before I start indexing the documents. At present it takes
about 30 minutes to re-index some of the types. During this time the search
feature doesn't work since my type in the index is almost empty!

To overcome this, here is the idea I have in my mind - While rebuilding
the index, add a temporary type (say SupplierA_temp for SupplierA), and
once I am done with the rebuilding I could delete the mapping for
SupplierA, and then renaming SupplierA-temp to SupplierA. Is that a
feasible solution? or is there a better solution?

Thanks
