Hi all,  
I have a little problem with highlight mechanism, there are already some  
posts on fuzzy + highlight but I don't find any solution to my problem.  
I use ES as part of keywords search engine development for a travel agency  
website.  
Basic requests use match + highlight and all works very good.  
But, when match does not find any result, I try to use flt to see there  
will be not similar results (i.e. a proper name miswritten, ...)

So, here an example of match request which works with highlight :

{  
"query": {  
"match": {  
"\_all": {  
"query": "N'Gorongoro",  
"operator": "and"  
}  
}  
},  
"highlight": {  
"order": "score",  
"fields": {  
"\_all": {},  
"title": {  
"number\_of\_fragments": 0  
},  
"themes": {  
"number\_of\_fragments": 0  
},  
"intro": {  
"number\_of\_fragments": 2,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"summary": {  
"number\_of\_fragments": 2,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"program": {  
"number\_of\_fragments": 3,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"hotel": {  
"number\_of\_fragments": 2,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"accommodations": {  
"number\_of\_fragments": 3,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"vehicles": {  
"number\_of\_fragments": 2,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"options": {  
"number\_of\_fragments": 2,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"extensions": {  
"number\_of\_fragments": 2,  
"fragment\_size": 75,  
"fragment\_offset": 25  
},  
"content": {  
"number\_of\_fragments": 3,  
"fragment\_size": 100,  
"fragment\_offset": 50  
}  
}  
}  
}

And there, an example of flt request which works but where there is not  
highlight :

{  
"query": {  
"flt": {  
"like\_text": "gorogoro"  
}  
},  
"highlight": {  
"order": "score",  
"fields": {  
"\_all": {},  
"title": {  
"number\_of\_fragments": 0  
},  
"themes": {  
"number\_of\_fragments": 0  
},  
"intro": {  
"number\_of\_fragments": 2,  
"fragment\_size": 50  
},  
"summary": {  
"number\_of\_fragments": 2,  
"fragment\_size": 50  
},  
"program": {  
"number\_of\_fragments": 3,  
"fragment\_size": 50  
},  
"hotel": {  
"number\_of\_fragments": 2,  
"fragment\_size": 50  
},  
"accommodations": {  
"number\_of\_fragments": 3,  
"fragment\_size": 50  
},  
"vehicles": {  
"number\_of\_fragments": 2,  
"fragment\_size": 50  
},  
"options": {  
"number\_of\_fragments": 2,  
"fragment\_size": 50  
},  
"extensions": {  
"number\_of\_fragments": 2,  
"fragment\_size": 50  
},  
"content": {  
"number\_of\_fragments": 3,  
"fragment\_size": 100  
}  
}  
}  
}

Does someone have any suggestion ?  
Thank you.
