Hi,

I'm new to elastic search and am wondering if there is a way to highlight on all fields.

Looks like highlighting requires me to explicitly specify the field names.  
My understanding is that if I want to highlight on all fields, I will have to use \_all but that requires me to store the \_all field that will increase index size and requires some mapping for \_all.

Is there any way to highlight on all fields without having to store extra data or mapping?

Any sample query will be appreciated.  
Thanks
