Highlighting on all fields

Elastic Stack Elasticsearch
1

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 mappings 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

You need to specify the field to highlight on, or, highlight the _all field
(Elasticsearch Platform — Find real-time answers at scale | Elastic).

Hi

you can also do like this. it worked like charm for me: use "*" instead of
"_all"

POST 123821/Encounters/_search
{
"query": {
"query_string": {
"query": "Test*"
}
},
"highlight" : {
"fields" : {
"*" : {}
}
}
}
