title: AWS - Dynamo Query Partition key List
body: <p>I'm new to AWS. Can I query the dynamo data on the same table where the Partition key(docType) equals to AA or BB or CC etc? I don't see &quot;OR&quot; or &quot;IN&quot; clauses in keyConditionExpression. Is there any way to achieve this? I'm using node.js  Thanks.</p>
