Elasticsearch script execution on missing field

Elastic Stack Elasticsearch
1

I am currently using ES version 0.19. For a feature requirement, I wanted
to execute script on missing field through terms facet. The curl which I
tried is something like below

{ "query": { "term": { "content": "deep" } }, "filter": { "and": { "filters": [ { "type": { "value": "twitter" } } ] } }, "facets": { "loca": { "terms": { "field": "countryid", "script": "doc['countryid']==null?1:doc['countryid'].value" } } } }

I assume that missing fields can be accessed by the condition
doc['countryid']==null. But it looks like this is not the way to identify
the missing field in script :frowning:

For which am always receiving response as missing

{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 6,
"successful" : 6,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
},
"facets" : {
"loca" : {
"_type" : "terms",
"missing" : 1,
"total" : 0,
"other" : 0,
"terms" : [ ]
}
}
}

Could anybody help me to get this correct.

Thanks in advance, Manoj

I think the correct way to see if there is a missing field is the following

doc['countryid'].empty == true

Check also:

btw why such an old version of ES?
