Hi folks, I'm new to mapping in ES and I have a need: I'm indexing some Documents, those documents can have a field or two that I do not want in the response but I want to be able to search on them (they should be indexed, not stored). What is the best way to do that? 1. What I understand is that: - set \_source.enabled to false - set store to true all on the "public" fields - query using fields[\*] 1. Another solution is to query and specify the fields I want explicitly: - query using a long list of fields[title, stuff, lot, of, stuff] 1. Yet another can be the new (kind of?) "excludes" and "includes" \_source options: - set \_source.excludes to [private\_data] I did'nt found lot of documentation about the "excludes" / "includes" options but they seems to be by far the best option for me, but what about performance? Sorting? What are the downside of "excludes" against a fields[] query? I am doing this right? Let me know! Thx !

The answer depends on this question: do you want to be able to reindex your documents using Elasticsearch as the source? In other words, if you need to change your index (eg you need to make some incompatible change to your mapping), would you create the new index by pulling data from the old index, or would you pull your data from some external data source? If an external data source, then map your \_source field to use 'excludes'. If you want to use Elasticsearch as the data source, then keep your \_source field intact, and either: - specify the fields you want returned with the fields parameter, or - use partial fields to strip out the parts of the source that you don't want returned See [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/search/fields/) clint -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
