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 -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, no real alias functionality, but you can rename fields on indexing using the index\_name property in your mapping. > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.
