GetVirtualDocumentRows
Retrieve the rows of the virtual document with the specified identifiers and the given effectiveAt date time.
Get virtual document rows merges multiple StructuredResultData items upserted with UpsertStructuredResultData for a single StructuredResultDataId.
Since an item of StructuredResultData is always upserted with a StructuredResultDataId, of which effectiveAt is a part, then merging across the asAt dimension is supported but not merging across the effectiveAt dimension.
