The post asks whether it is better to use the same embedding model for indexing and querying. The comments indicate that it is not only important, but also required to use the same dimension embedding model for indexing and querying, otherwise there would be a dimension mismatch issue. The community members agree that this makes sense.
It is not only imp but also required to use the same dimension embedding model for indexing and querying. Other wise you'd get dimension mismatch issue
