How can I add filter to Completion Suggester in ElasticSearch?

Question

Does anyone know how to add filter to suggester?

This works very well:

{ "headline-suggest" : {     "text" : "n",     "completion" : {         "field" : "headline_suggest"     } } 

but I want force ElasticSearch to build list of suggestions from subset of data, like:

{ "headline-suggest" : {     "text" : "n",     "completion" : {         "field" : "headline_suggest"     } }, "filter" : {     "term" : { "mydifferentfield" : "someword" } } } 

How can I achieve it?

(I'm using elasticsearch 0.90.5)

As per version 1.2.0, you can add context to your suggester and obtain filtered suggestions.

i am not really sure about that, but i think that you can not filter a suggest request in elasticsearch.

from what i read this is due to the kind of data structure it is stored in. elasticsearch calculates statistical data on the terms to suggest at index time and uses those for the suggest operations.

did you try performing a normal query in combination with a suggest? maybe there is a different outcome to that?

curl -s -XPOST 'localhost:9200/_search' -d '{   "query" : {     ...   },   "suggest" : {     ...   } }'
