Different document types with shared field names

Elastic Stack Elasticsearch
1

I'm trying to understand this correctly. If I have two separate document
types (my_type_1 and my_type_2), and they both have a field (my_field)
which is defined different (string not analyzed and long), I can't do a
search on my_type_1 sorting by my_field if there are any documents in the
index of my_type_2 that have multiple values in my_field?

Because of this, I have to prefix all my fields with the document type...
which seems wrong. Am I missing something?

Thanks for the help.

Hello Christopher,

You might be able to reference the specific field you want with something
like my_type_1.my_field, although it shouldn't work for faceting (source
here http://www.elasticsearch.org/guide/reference/mapping/).

The reason for it is that all your fields from all your types end up in the
same Lucene indices (shards), so if you have the same field name in
multiple types, it's best to have the same settings. Otherwise, you'll bump
into the behavior you're reporting here.

Best regards,
Radu
