Thanks Jan.
But I read that the field that is being collapsed on must be a single
valued String, Int or Float. As I'm required to get the distinct results
from "content" field that was indexed from a rich text document, I got the
following error:
"error":{
"msg":"java.io.IOException: 64 bit numeric collapse fields are not
supported",
"trace":"java.lang.RuntimeException: java.io.IOException: 64 bit
numeric collapse fields are not supported\r\n\tat
Is it possible to collapsed on fields which has a long integer of data,
like content from a rich text document?
Regards,
Edwin
