# SourceFields

A list of fields that you want to use to generate the QuerySummary. Separate multiple fields with commas (there must be no space before or after a comma).

This parameter overrides the configured SourceType fields for a single action. You can use it to generate a query summary from alternative fields, for example if your SourceType fields include a product description and you want to generate a query summary based on product reviews instead.

If you set `SourceFields` but the fields that you specify are not valid, IDOL Server does not generate a query summary.

Actions: | Query
Type: | String
Default: | The configured SourceType fields
Example: | `SourceFields=*/REVIEWS,*/COMMENTS`
