# Train the store's learned scoring function

`POST /v1/stores/{store_identifier}/lsf/train`

Queue a learned-scoring-function training run for a store.

signals for the store's captured searches and trains new weights when
enough signalled elements exist, exactly like the scheduled daily run.

    store_identifier: The ID or name of the store.

Returns:
    StoreLsfTrainingQueued: Confirmation that the run was queued.
