It highlights differences without merging or saving them."},{"question":"Can I use it on semantic search results?","answer":"Yes. Select two matches and compare the attributes returned by the vector index. Unprojected base-table attributes are not fetched automatically."}],"related":["dynamodb-bulk-edit","dynamodb-semantic-search","dynamodb-copy-items"]}},
