Hello,

The highlighting feature does not seem to work when I use Fuzzy Like  
This query. I'm not sure if the way I constructed the query is correct  
or not. Please point out to me what I'm missing in order for the  
highlighting feature to work?

Using "query\_string" the highlighting works --\> [https://gist.github.com/1065424](https://gist.github.com/1065424)

Using "flt" the highlighting is not working --\> [https://gist.github.com/1065403](https://gist.github.com/1065403)

Following are the mapping or articles and  
{  
"articles": {  
"properties": {  
"tags": {  
"index": "not\_analyzed",  
"type": "string"  
},

"content": {  
"store": "yes",

I had some issue with a prefix query. It has been fixed with my patch:

> <https://github.com/elastic/elasticsearch/pull/1065>
>
> Prefix queries needs to be rewritten so the highlighter can work. So the pull re…quest.
> 
> The highlight of prefix queries doesn't highlight the prefix but the full word. I have written some code on the client side to change the highlighted words. For instance, searching "ski", lucene highlight "\<\>skiing\</\>", "\<\>skin\</\>" or "\<\>skills\</\>". So my code change the highlighted parts to be: "\<\>ski\</\>in", "\<\>ski\</\>n" or "\<\>ski\</\>lls". This code may be interesting to be on the server part, but I don't know where. If you think it is interesting, let me know.

Probably some patch will be needed for the fuzzy query.

Hello,

Apologies for not updating this thread. I fixed the highlighting issue  
by making sure to add at following parameters in "title" and  
"content"

term\_vector = with\_positions\_offsets
