Hi all,
I'd like to know if it is possible to have a field, which would be available for all the documents inside one index and having the same type? I understand that there could be an obvious method (though utterly unefficient) in which case we could have a certain field for all the documents and update constantly that field for all the documents. But as far as efficiency is considered also, it would be great to have a field "outside" all the documents that would also be possible to use as a filter. Does anyone know if there is actually such a feature in ElasticSearch or something close to that?
