Proposed fix: [Haystack InMemoryDocumentStore] DocumentStoreError "The embedding size of the query should be the same as the embedding size of the Documents" (query/document embedder mismatch)
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Use the same model for the TextEmbedder and DocumentEmbedder; re-embed/re-index documents after changing models.
Option: Align embedder models and re-index [evidence: official_recommended_action]
Applies when: RAG pipelines
Steps:
1. Use identical model names for SentenceTransformersTextEmbedder and SentenceTransformersDocumentEmbedder
2. Re-run indexing
Expected: Retrieval works
Evidence basis (self-declared by the contributing chat client): untested.
