Struct FastEmbed

Source 
pub struct FastEmbed { /* private fields */ }
Available on crate feature fastembed only.
Expand description

A wrapper around the FastEmbed library for text embedding.

Supports a variety of fast text embedding models. The default is the Flag Embedding model with a dimension size of 384.

A default can also be used for sparse embeddings, which by default uses Splade. Sparse embeddings are useful for more exact search in combination with dense vectors.

Into is implemented for all available models from fastembed-rs.

See the FastEmbed documentation for more information on usage.

FastEmbed can be customized by setting the embedding model via the builder. The batch size can also be set and is recommended. Batch size should match the batch size in the indexing pipeline.

Note that the embedding vector dimensions need to match the dimensions of the vector database collection

Requires the fastembed feature to be enabled.
