In a parent, child doc mapping, is it possible to highlight the  
matches in the child document?

I doubt it is an open issue : [[Feature request] Highlighting with parent/child queries · Issue #1764 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/1764)

Its not possible as of now.  
You will have to do the task in 2 web calls.  
First one which runs the has\_children query. Here you need to collect the  
docid.  
Second web call should have \_parent with all the matching doc ID previously  
gathered

Thanks

In a should query I'm doing the following to highlight the children hits. However I'm experiencing som issues highlighting the hits from the parent at the same time - but hope this will solve your issues.

You can leave the filters - they are only for the purpose of fetching the active children in my setup.

"query": {  
"bool": {  
"should": [  
{  
"has\_child": {  
"type": "TYPE",  
"score\_mode": "max",  
"query": {  
"filtered": {  
"query": {  
"multi\_match": {  
"query": "QUERY",  
"fields": ["CHILD\_FIELD\_1", "CHILD\_FIELD\_2"]  
}  
},  
"filter": {  
"term": {  
"active": true  
}  
}  
}  
},  
"inner\_hits":{  
"highlight": {  
"fields": {  
"CHILD\_FIELD\_1": {}  
}  
}  
}  
}  
}  
]  
}  
}
