I am using Elastic Search 1.3.5.  
I have fields like filename, foldername and content. In query I am trying  
to highlight matched content.

In Query if keyword only matches in content then keyword is highlighted and  
its becoming bold. However if keyword matches in (filename or foldername)  
and content then content is not highlighted.  
What I am missing here?

Query sample,

{  
"query": {  
"filtered": {  
"query": {  
"bool": {  
"should": [  
{  
"match": {  
"fileName": {  
"query": "document",  
"boost": 4  
}  
}  
},  
{  
"match": {  
"folderName": {  
"query": "document",  
"boost": 3  
}  
}  
},  
{  
"match": {  
"fileName.trigram": {  
"query": "document",  
"boost": 2,  
"minimum\_should\_match": "50%"  
}  
}  
},  
{  
"match": {  
"content": {  
"query": "document",  
"boost": 5  
}  
}  
},  
{  
"match": {  
"folderName.trigram": {  
"query": "document",  
"boost": 1,  
"minimum\_should\_match": "50%"  
}  
}  
}  
]  
}  
},  
"filter": {  
"and": [  
{  
"term": {  
"businessId": 1  
}  
},  
{  
"term": {  
"deleted": false  
}  
},  
{  
"bool": {  
"should": [  
{  
"term": {  
"folderPath": "/shared/documents"  
}  
},  
{  
"prefix": {  
"folderPath": "/shared/documents/"  
}  
}  
]  
}  
}  
]  
}  
}  
},  
"highlight": {  
"fields": {  
"content": {  
"fragment\_size": 150,  
"number\_of\_fragments": 0,  
"no\_match\_size": 150  
}

Can you post an example document? Can you post your mapping? Mapping is  
important because depending on how your mapping is set up you'll get a  
totally different highlighter implementation.
