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/](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 [http://sematext.com/](http://sematext.com/) -- Elasticsearch -- Solr -- Lucene On Wed, May 8, 2013 at 1:01 AM, Christopher J.
