   Hi @kaivalnp, thanks for this contribution!
   
   My question is why do we have two thresholds, one for grap traversal (used 
to decide if it's worth exploring a candidate neighbour) and the resulting 
threshold (used to accept or not a result)?
   The lower the traversal threshold, the longer the search but the more likely 
the possibility of finding more vectors within the accepted threshold.
   The higher the traversal threshold, the shorter the search but you are less 
likely to find all vectors within the accepted threshold.
   Is it a matter of tuning? Did I get it right?
