Problem:
You are trying to run an ElasticSearch query like
{ "query": { "missing" : { "field" : "myfield" } } }
to find documents that do not have myfield
.
However you only see an error message like this:
elasticsearch.exceptions.RequestError: RequestError(400, 'parsing_exception', 'no [query] registered for [missing]')
Solution:
As the ElasticSearch documentation tells, us, there is no missing
query! You instead need to use an exists
query inside a must_not
clause:
{ "query": { "bool": { "must_not": { "exists": { "field": "myfield" } } } } }
