Hi, I have a problem with the highlighting feature. In my query I use  
dis\_max, constant\_score, bool and query\_string together. It works when I  
use for example only the terms query or only the query string query. Are  
there any restrictions on the use of highlighting?

ES versions: 0.18.1, 0.19.9

{  
"sort": [  
{  
"\_score": "desc"  
},  
{  
"name": "asc"  
}  
],  
"from": 0,  
"size": 50,  
"highlight": {  
"fragment\_size": 0,  
"number\_of\_fragments": 0,  
"fields": {  
"names": {},  
"content": {}  
}  
},  
"query": {  
"dis\_max": {  
"tie\_breaker": 0.0,  
"queries": [  
{  
"constant\_score": {  
"query": {  
"bool": {  
"should": [  
{  
"bool": {  
"must": [  
{  
"query\_string": {  
"query": "foo AND NOT bar",  
"fields": [  
"names",  
"content"  
]  
}  
},  
...  
]  
}  
}  
]  
}  
},  
"boost": 20.0  
}  
},  
...  
]  
}  
}  
}

Problem solved. I declare the following in the mapping for the fields I  
want to highlight:

:term\_vector =\> "with\_positions\_offsets", :store =\> "yes"

This enables the fast vector highlighter.
