How to define a custom mapping in the creation of an index in ElasitsearchDocumentStore

[jesusfbes]

Hello,

I have seen that in Haystack 1.x you could define a custom mapping for an index in ElasticSearch in ElasticsearchDocumentStore constructor (in particular you could define analyzers for certain fields). I was not able to find that option in version 2.X. Is is now possible to do it?

Thank you very much.

@jesusfbes thanks for this question. Let me check internally.

Hey @jesusfbes, as of now it's not possible to use a custom mapping for the ElasticsearchDocumentStore.

I created an issue to keep track of this feature request.

Thank you very much for the response.

Hey guys! Is there an update on this issue?

[vblagoje]

Seems to be implemented, no? deepset-ai/haystack-core-integrations#655
Not my area of expertise and codebase knowledge - please let everyone know on this thread if the solution works for you @jesusfbes and @george-perakis

Should be in the latest elasticsearch-v0.5.0

I updated to the latest haystack-ai but it didn't upgrade the elasticsearch to v0.5.0. I did it manually. It now works. Thanks a lot @vblagoje

I cannot try it at the moment but thank you for merging this feature

Yes all integrations are independent in release cycles. Thanks for participating and voicing for this issue 🙏 Onward
