Hi,I'm a new to ES, our project is about email.
Recently, we try to index attachments with Attachment Type. What confused
us is that Although we only need the content index, ES still store file's
base64 string in _source. I am afraid that this may cost a lot of hard disk
space.
Is there some way to solve the problem？Is it possible to index content and
discard base64 string？
Thanks,
Shiny ke
