Hi,

I'm still working on a fast highlighted autocomplete.

Imagine that I query 'andr'

'Alexandre' and 'Andre' are matching but both terms are fully highlighted. I  
would like to hightlight only the letter I typed.

Here is my mapping :

{  
2 "usr" : {  
3 "properties" : {  
4 "title" : {  
5 "type" : "string",  
6 "term\_vector" : "with\_positions\_offsets"

7 }  
8 }  
9 }  
10 }  
11 }

Here is the query :

array('query'=\>array('bool'=\> array(  
'must' =\>  
array("query\_string"=\>array('default\_field'=\>"title",  
'default\_operator'=\>'AND', 'query'=\>"_$str_")),  
'minimum\_number\_should\_match'=\> 1,  
'boost' =\> 1.0  
)  
),  
'highlight' =\>  
array('fields'=\>array('title'=\>array('fragment\_size'=\>150,'number\_of\_fragments'=\>3)))  
);

Any clue ?

Thanks

I think you could try to use nGram analyzer and custom tokenizer. I found [answer](http://stackoverflow.com/questions/21310610/highlighting-part-of-word-in-elasticsearch) on stackoverflow. I hope it will help you.
