# Refreshing datasets in a Quick Sight topic
Refreshing datasets

When you add a dataset to a topic, you can specify how often you want that dataset to refresh. When you refresh datasets in a topic, the index is refreshed for that topic with any new and updated information. 

Your datasets aren't replicated when you add them to a topic. An index of unique string values is created and metrics are not indexed. For example, measures stored as integers are not indexed. Questions asked always fetch the latest sales metrics based on data in your dataset.

For more information about refreshing the topic index, see [Refreshing Quick Sight topic indexes](topics-index.md)

You can set a refresh schedule for a dataset in a topic, or refresh the dataset manually. You can also see when the data was last refreshed.

1. On the **Summary** page, choose **Data**. Then, under **Datasets**, expand the dataset that you want to set a refresh schedule for.

   + If the dataset is a SPICE dataset, select **Refresh topic when dataset is imported into SPICE**.

     Currently, hourly refresh SPICE datasets aren't supported. SPICE datasets that are set to refresh every hour are automatically converted to a daily refresh. For more information about setting refresh schedules for SPICE datasets, see [Refreshing SPICE data](refreshing-imported-data.md).
