Hello. I'm creating an Elasticsearch plugin that creates a new field type
(similarly to how the elastic-mapper-attachments plugin does here
<https://github.com/elasticsearch/elasticsearch-mapper-attachments/blob/master/src/main/java/org/elasticsearch/index/mapper/attachment/AttachmentMapper.java>).
However, I need to store sub-objects and several instances of a nested
object. For instance, for a type mapping like this:
{
"my_elastic_type": {
"properties": {
"my_field": {
"type": "my_new_field_type",
"stuff": {
"reference": {
"index": "myIndex",
"type": "ref",
}
},
"stuff2": {
"reference": {
"index": "myOtherIndex",
"type": "ref",
}
}
}
}
}
}
and indexing a document like this:
{
"my_field": "text here"
}
I would like the store the equivalent to the following in the index:
{
"stuff": {
"calcField1": "foo",
"calcField2": "baz",
"nestedObjs": [
{
"nestedField1": "info",
"nestedField2": "data"
},
{
"nestedField1": "info",
"nestedField2": "data"
}
]
},
"stuff2": {
"calcField1": "foo2",
"calcField2": "baz2",
"nestedObjs": [
{
"nestedField1": "info2",
"nestedField2": "data2"
},
{
"nestedField1": "info2",
"nestedField2": "data2"
}
]
},
}
I'm having a lot of trouble figuring out how to add non-simple fields in my
plugin. I can't find any documentation of how to develop an Elasticsearch
plugin.
Thanks for any help.
