Highlight filter queries

Elastic Stack Elasticsearch
1

Highlight works for the following query. But, i want to highlight the query values present in the filter too. Do i need to entirely change my query structure for that or am i missing out anything in this??

curl "10.237.247.16:9200/cai/_search?pretty=true" -d '{
"query": {
"filtered": {
"query": {
"field": {
"complete": "PATIENT_MERG_2"
}
},
"filter": {
"bool": {
"must": [
{
"query": {
"wildcard": {
"unanalyzedtrace": "23:01:7"
}
}
},
{
"query": {
"wildcard": {
"unanalyzedtrace": "ICP.IR1.MANUALMERGE.IN"
}
}
}
]
}
}
}
},
"highlight": {
"fields": {
"complete": {},
"unanalyzedtrace":{}
}
}
}'

RESPONSE

}
} ]
}
}

When tried to change query to work on 'unanalyzedtrace' instead of 'complete', the whole value gets highlighted.

you need use "inner hits" to highlight the content. for example:
"inner_hits": {
"highlight": {
"fields": {
"details":{
"type": "plain",
"force_source" : true,
"fragment_size": 20,
"number_of_fragments": 3
}
}
},
"size":1,
"sort": { "praiseCount": "desc"}
}
