Field name alias

Elastic Stack Elasticsearch
1

Hi,

is there something I would call "field name alias"? Suppose I have two
indeces/types with two different document schemas. One where the title of
the document is found in the field "title" and another where the field is
called "headline". But at query time I only want to query the field-(alias)
"title" but get both matching types of documents.

document A:
{ "title": "hello" }

document B:
{ "headline": "hello" }

pseudo-query:
{
"term" : { "titleAlias" : "hello"}
}

Cheers

Hey,

no real alias functionality, but you can rename fields on indexing using
the index_name property in your mapping.

Hope this helps
