You can do it by 2 ways :
1) using multiple fields in a single facet result :
example for single fields facet :
curl -X GET "http://localhost:9200/sales/order/_search?pretty=true" -d '{
"query": {
"query_string": {
"query": "shohi*",
"fields": [
"billing_name"
]
}
},
"facets": {
"facet_result": {
"terms": {
"fields": [
"status"
],
"order": "term",
"size": 15
}
}
}
}'

"query": {
"query_string": {

]
}
},
"facets": {
"facet_result": {
"terms": {
"fields": [
"status",
"customer_gender",
"state"
],
"order": "term",
"size": 15
}
}
}
}'
2) Use multiple facet result set :
curl -X GET "http://localhost:9200/sales/order/_search?pretty=true" -d '{
"query": {
"query_string": {
"query": "*",
"fields": [
"increment_id"
]
}
},
"facets": {
"status_facets": {
"terms": {
"fields": [
"status"
],
"size": 50,
"order": "term"
}
},
"gender_facets": {
"terms": {
"fields": [
"customer_gender"
]
}
},
"state_facets": {
"terms": {
"fields": [
"state"
],
,
"order": "term"
}
}
}
}'
