title: How to create an Attribute value for range condition in DynamoDB for GSI
body: <p>I want to search the GSI in my DynamoDB. However I would like to search with KeyConditionExpression. In this case I won't be able to search by  RangeKeyCondition as I get an error: <code>The range key conditions can only be specified when the key condition expression is not specified.</code></p>
  
  <p>I think the way to go about this is using withExpressionAttributeValues, but I am not sure how to use it for a range condition. I have not been to find any examples. </p>
