Support for field exclusion from source [DATAES-195]

[spring-projects-issues]

István Nagy opened DATAES-195 and commented

Elasticsearch allows us to specify field level exclusions when creating a mapping. See: https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-source-field.html#include-exclude

This functionality allows us to create a so called "indexed but not stored" kind of document fields. The @Field annotations existing store attribute is not equivalent with this.

Spring Data ES currently lacks this feature in the document annotations, It should be possible to enable it using a custom mapping configuration file however it would be more expressive to specify this on the @Field annotation directly.

Eg.:

code
@Field(type = FieldType.String, excludeFromSource = true)
private String indexOnlyField;
code
