TODO

Before pre-release

Pre-release

• With the help of this CI running on rc0, define in which SDKs we have to update the tests

  ⚠️ If possible, this step is done before pre-release, once the feature is ready thanks to the prototype released by the engine team
  • JS
  • PHP
• Update integrations having failing test suites with the new RC of Meilisearch (refer to this CI)
  • JS
  • PHP
  • Python
  • Go
  • Dart
• Add code samples for the chosen up-to-date integrations with the new version of Meilisearch
• Update the library version of the related integrations and prepare the changelogs

Release day

• ⚠️ for one of these SDKs (Dart, Python, Go) that don't have integrated the new vector search, create appropriate communication in issues and release notes!
• Release the integrations
  • JS
  • PHP
• Merge PR related to vector search communication for
  • Python
  • Go
  • Dart
• Merge the related PR in K8s repository
• Publish DevOps tools:

(?) Python for vector search v2

I verified that at a minimum the python tests will need updating for vector search.

test_vector_search result:

meilisearch.errors.MeilisearchApiError: MeilisearchApiError. Error code: missing_search_hybrid. Error message: Invalid request: missing `hybrid` parameter when both `q` and `vector` are present.. Hint: It might not be working because you're not up to date with the Meilisearch version that search call requires. Error documentation: https://docs.meilisearch.com/errors#missing_search_hybrid Error type: invalid_request

I've got the same error when I do vector search using python sdk 0.30.0 and the version of Meilisearch is 1.6.2:
meilisearch.errors.MeilisearchApiError: MeilisearchApiError. Error code: missing_search_hybrid. Error message: Invalid request: missing hybridparameter when bothqandvector are present..

Did you include the hybrid parameter with your search?

@sanders41 I'm following this tutorial and I'm get the same error and there is nothing about the error code in the docs.

@sanders41 I'm following this tutorial and I'm get the same error and there is nothing about the error code in the docs.

There were breaking changes to vector search in 1.6. I have not used LangChain and don't know much about it, but looking at the example provided it doesn't look like LangChain is compatible with Meilisearch 1.6+ vector search.

@Strift I'm not sure if LangChain needs to be updated, if the tutorial needs updating to mention it works with Meilisearch >=1.3 <1.6, or if it is possible somehow to make it work with Meilisearch 1.6+?

I tried to add an embedder to my meilisearch instance but I got the error bellow. When we add an embedded to meili, it will generate vectors for all documents or only use to embedding queries?

  "message": "The `_vectors` field in the document with id: `\"0c297f065a8c46cab12857ca5999c371\"` is not an object. Was expecting an object with a key for each embedder with manually provided vectors, but instead got `[-0......."

Hello @kauly,

If you want to use LangChain, please use a previous Meilisearch version, like v1.5.

Our current LangChain integration is intended for v1.3, v1.4, and v1.5. @CaroFG is currently updating our LangChain integration. After this, we'll update the tutorial too. 🙏

Thanks @sanders41 for the heads up.
