How to index an array of a nested type in Elasticsearch?

Question

I am working on ElasticSearch. Here I wanted to index an array of nested type fields via the JAVA api. Can anyone give an example. I tried a little, but they could not.

XContentBuilder xb1 = XContentFactory.jsonBuilder().startObject(); XContentBuilder xb2 = XContentFactory.jsonBuilder().startObject(); xb1.startArray("eventnested"); for(int j=0;j<2;j++) { xb2.field("event_type",eventType); xb2.field("event_attribute_instance",eventInstance); xb2.startArray("attributes"); for(int i=0;i<2;i++) { XContentBuilder xb3 = XContentFactory.jsonBuilder().startObject(); xb3.field("event_attribute_name", attrName); xb3.field("event_attribute_value", attrValue); xb2.value(xb3.copiedBytes()); } xb1.value(xb2.copiedBytes()); } 

After indexing the data, when I read the answer, the data of a specific area looked like

"Eventnested.event_type": [ "EyJldmVudF90eXBlIjoiUXVvdGF0aW9uIiwiZXZlbnRfYXR0cmlidXRlX2luc3RhbmNlIjoiMSIsImF0dHJpYnV0ZXMiOlsiZXlKbGRtVnVkRjloZEhSeWFXSjFkR1ZmYm1GdFpTSTZJbkJsY25OdmJpQWlMQ0psZG1WdWRGOWhkSFJ5YVdKMWRHVmZkbUZzZFdVaU9pSkxZWGtnVFdGcmFIVmlaV3hoSW4wPSJdLCJhdHRyaWJ1dGVzIjpbImV5SmxkbVZ1ZEY5aGRIUnlhV0oxZEdWZmJtRnRaU0k2SW5GMWIzUmxJQ0lzSW1WMlpXNTBYMkYwZEhKcFluVjBaVjkyWVd4MVpTSTZJblJvWlNCaWIza2djbUZ3WldRZ2RHaGxJSEJoYVhJZ2IyNGdiblZ0WlhKdmRYTWdiMk5qWVhOcGIyNXpMQ0IzYVhSb0lIUm9aU0JzWVhSbGMzUWdhVzVqYVdSbGJuUWdZbVZwYm1jZ2IyNGdSbkpwWkdGNUluMD0iXX0 =", "eyJldmVudF90eXBlIjoiUXVvdGF0aW9uIiwiZXZlbnRfYXR0cmlidXRlX2luc3RhbmNlIjoiMSIsImF0dHJpYnV0ZXMiOlsiZXlKbGRtVnVkRjloZEhSeWFXSjFkR1ZmYm1GdFpTSTZJbkJsY25OdmJpQWlMQ0psZG1WdWRGOWhkSFJ5YVdKMWRHVmZkbUZzZFdVaU9pSkxZWGtnVFdGcmFIVmlaV3hoSW4wPSJdLCJhdHRyaWJ1dGVzIjpbImV5SmxkbVZ1ZEY5aGRIUnlhV0oxZEdWZmJtRnRaU0k2SW5GMWIzUmxJQ0lzSW1WMlpXNTBYMkYwZEhKcFluVjBaVjkyWVd4MVpTSTZJblJvWlNCMFpXVnVZV2RsY2lCb1lYTWdZbVZsYmlCd2JHRmpaV1FnYVc0Z1lTQnpZV1psZEhrZ2FHOXRaU0JoYm1RZ2 QybHNiQ0JpWlNCamFHRnlaMlZrSUh kcGRHZ2djbUZ3WlNKOSJdfQ == "

 XContentBuilder xb = XContentFactory.jsonBuilder().startObject(); xb.startArray("eventnested"); for(int j=0;j<2;j++) { xb.startObject(); xb.field("event_type", eventType); xb.field("event_attribute_instance", eventInstance); xb.startArray("attributes"); for(int i=0;i<2;i++) { xb.startObject(); xb.field("event_attribute_name", attrName); xb.field("event_attribute_value", attrValue); xb.endObject(); } xb.endArray(); xb.endObject(); } xb.endArray();
