How could i manage types in new versions ? another way?

[Anibal_Ardid (Anibal)]

Hi !
I'm new on elasticsearch indexing.
And i'm trying to migrate from v5 to v8, i know this is a big change and challenge.

I read about types are deprecated now.

So , how could i manage my data ?

Now I have 1 index per website, and each index has different types of information, for example:
multimedia,
people,
publications,
resources.

In v5 we have organized in types.

How could I manage it now ?

I used php, latest elasticsearch composer library, and custom php code to create map, index, etc

config:

I'd suggest that you read Removal of mapping types in Elasticsearch 6.0 | Elastic Blog

[Anibal_Ardid (Anibal)]

thanks for your quickly response.

Reading that, an alternative could be add "type" or "post type" property/field to each property, correct ?

[dadoonet (David Pilato)]

Yes that's one of the solutions. Or one index per type which is better if you have a lot of fields which are not shared by the different types.

But may be explain a bit more what are looking like typical documents and we might find other ideas

[Anibal_Ardid (Anibal)]

well ... this is a WordPress headless cms with some different customs post types. And a lot of information in each of them.
Now all are indexed by some custom process.

And i'm trying to use it on ES 8.6

[Anibal_Ardid (Anibal)]

For example now , I added item_type field to config and settings, and also to body that i'm indexing, and I have this error, only after add item_type field O_O

{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to parse"}],"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"illegal_argument_exception","reason":"Failed to parse value [analyzed] as only [true] or [false] are allowed."}},"status":400}

It was fixed changing:
"match_mapping_type":"string",
to:
"match_mapping_type":"boolean",
