Problem with Ingest Attachment Processor Plugin

I am new to this plugin and need your help.

This is what I do:

  1. Create index:
PUT localhost:9200/myindex
  1. And mappings:
PUT localhost:9200/myindex/mytype/_mapping
	"messages": {
	  "properties": {
		"subject": {"type": "string"},
		"sender": {"type": "string"},
		"receiver": {"type": "string"},
		"body": {"type": "text"}
  1. Now I create attachment by:
PUT http://localhost:9200/_ingest/pipeline/attachment
   "description" : "Extract attachment information",
   "processors" : [
	   "attachment" : {
			"field" : "data",
			"indexed_chars" : -1
  1. I add some data and it works fine with searching etc.

  2. But when I add an attachment to my previously added data like this:

PUT http://localhost:9200/myindex/mytype/1?pipeline=attachment
	"data": "some base64 data"

Then it overrides my whole previuosly added data and I am unable to search in my index.

What am I doing wrong? Please help.


you need to supply the full document here and not just the field you want to add, when you use the Index API

Ingest plugin does not support partial updates. So you need to provide the full JSON document:

  "data": "BASE64 HERE",
  "subject": "foo",
  "sender": "foo",
  "body": "foo"

PS: note that you should use text in your mapping and not string.

Sounds like @spinscale beat me on that one! :stuck_out_tongue:

OMG! So simple :slight_smile:

Why should I use text?

When I want to use pipeline in PHP what should I do?
Code below doesn't work:

$params = [
    'index' => 'myindex',
    'type' => 'mytype',
    'id' => '1',
    'body' => [
		'data' => 'BASE64_DATA',
		'subject' => 'test',
		'sender' => 'test',
		'body' => 'test',

I found a solution.
I have to use 'pipeline' => 'attachment' in my $params and then index it normally.
