title: Query all items in DynamoDB from a given hash key with a hash-range schema using java sdk
body: <p><strong>EDIT:</strong>
  I was actually incorrect. I was querying the table when I meant to query an index which explains my error. Vikdor's solution is a valid one though.</p>
  
  <p><strong>ORIGINAL:</strong>
  I have a table with a Hash-Range key schema in DynamoDB. I need to be able to get all items associated with a specific hash key but it seems to require a range key condition. My issue is I want EVERY range key but there is no wildcard option. As of right now my range key is a string and the only way I could think to do this is by querying all range keys greater or equal to the smallest ascii characters I can use since the documentation says it sorts based on ascii character values.</p>
  
  <p>I looked into scanning but it appears that simply will read the entire table which is NOT an option.</p>
  
  <p>Is there any better way to query for all values of a hash key or can anyone confirm that using the method with the ascii character will work?</p>
