Hi all,

I am using highlight function in ES 1.0.1. I found a very strange situation  
as follow:

I want to highlight the field "group.\* " which is the inside a  
dictionary, whose mapping is

{"properties": {

> "group":  
> { "type": "object",  
> "dynamic": false,  
> "include\_in\_all": true,  
> "properties": {  
> "data": {"type": "string", "index": "analyzed", "analyzer":  
> "name\_analyzer", "term\_vector": "with\_positions\_offsets",  
> "fielddata":{"format": "disabled"}},  
> "data\_2": {"type": "string", "index": "analyzed", "analyzer":  
> "nickname\_analyzer", "term\_vector": "with\_positions\_offsets",  
> "fielddata":{"format": "disabled"}},  
> ....(skip)  
> }  
> }  
> }  
> }

The analyzers of each field inside "group" are all different.

I query the word "Adobe" and I got the following result:

"highlight": {

> ```
> "group.data": [
> "I want it all, and I want it now 106\n\nUsing the 
> 
> ```
> 
> _Adobe_ ActionScript 3 SDK for Facebook platform 106\nTime",  
> "– obtaining data in pages 126\nTime for action –  
> _adding_ limit and offset to GraphRequest instances 128",  
> "requesting data based on date 131\nTime for  
> action – _adding_ since and until to GraphRequest instances  
> 133\nTime"  
> ]  
> }

by using the highlight command:

{'highlight': {'fields': {'group.\*': {'fragment\_size': 100, 'number\_of\_fragments':

> 3}}}}

As you saw, it highlight the "adding" word. I cannot understand why this  
comes.  
And I am pretty sure the analyzer of "group.data" field cannot normalize  
"Adobe" and "adding" into same form.

Any explanations? Please help me to understand what happened.

Thanks.

Ivan

The query command I used is as

{'multi\_match': {'fields': ['\_all', 'name', 'group.\*'],

> 'operator': 'and',  
> 'query': 'Adobe'}}

I doubt the problem might be because the various analyzers of the  
"group.\*".

What is the analyzer to be used during the highlight?

For people that face the same problems, it's because the analyzers used in  
highlight is included all the ones of the fields in the query if you don't  
turn require\_field\_match to true.

FYI.
