Yes. You're right. And the error message is really clear : {"error":"InvalidIndexNameException[[MYINDEX] Invalid index name [MYINDEX], must be lowercase]","status":400} So, I think you can not uppercase it ! David.

hi dadoonet i think this is an issue when we don't create index name with capital letter then how we can make field index in mapping.. Regards, Sumit Gupta ---

Not really I understand the connection between the index name having to be lowercase, and a specific field?

hi shay i mean to say that if we don't create the name of index to be in uppercase that means in mapping if we have any filed that is in uppercase then according to index not be in uppercase we don't define "index":"yes" for this field.... Regards, Sumit Gupta ---

What? There is the index name, this /[index\_name]/... (which has to be in lower case), then there is the field name in the document you index, which can have any casing. Then, there is the mapping of a field called index. What are you talking about?

Shay - Sorry to revive and old thread. Why the restriction on capital letters and index names? Also, are there other characters or classes that can't be used in an index name?
