Review Comment:
   Thanks for the suggestion! This should indeed give us a good speed up if we 
don't have to linearly scan docBuffer to locate. However, as I'm trying not to 
load the subsequent block since callers still need to be in current block 
(state) for nextDoc/advance, we may not be able to optimize for 
multiple-block-consecutive-docs scenario?
