Hi,

I've successfully installed Carrot2 plugin  
([https://github.com/medcl/elasticsearch-carrot2](https://github.com/medcl/elasticsearch-carrot2)) and make some test via GUI  
(elasticsearch head plugin).

I'm trying to prepare and execute "query" using Java client but I'm having  
troubles.

CURL version works as expected:

curl -XPOST [http://localhost:9200/elasticsearch\_resources/\_carrot2?carrot2.fetch\_size=1800&carrot2.language=ENGLISH&carrot2.title\_fields=title&carrot2.summary\_fields=snippet&carrot2.url\_field=url&carrot2.attach\_detail=true](http://localhost:9200/elasticsearch_resources/_carrot2?carrot2.fetch_size=1800&carrot2.language=ENGLISH&carrot2.title_fields=title&carrot2.summary_fields=snippet&carrot2.url_field=url&carrot2.attach_detail=true)  
-d'  
{  
"query": {  
"bool": {  
"should": [  
{  
"match\_all": {}  
}  
]  
}  
},  
"from": 0,  
"size": 10  
}  
'

How can we prepare such a query from Java client (custom url with  
parameters)?  
How can I query custom plugin with Java API?

Thanks.

I am not sure about the Java API, but I think this is sort of language  
agnostic. For eg., for the perl client, I had to modify the code to  
support requests for the carrot plugin ( which mainly involved  
defining the params for the request and the method ). I am not sure if  
there is a uniform/base api for (any) plugins to interface with.
