generator repeats same result several times.

Hi
I just tried out your search capability where I have a short "needle" string of 14 characters, but a very long "haystack" string of over 50000 characters. The routine is finding the needle very quickly, but I am getting the same string detected multiple times. Here is the result for a distance of 5...

ngramLen < 10
needle George Latimer
result [
  { start: 9599, end: 9613, dist: 5 },
  { start: 9599, end: 9613, dist: 5 },
  { start: 9599, end: 9613, dist: 5 },
  { start: 9598, end: 9613, dist: 5 },
  { start: 9598, end: 9613, dist: 4 },
  { start: 9598, end: 9613, dist: 4 },
  { start: 9598, end: 9613, dist: 5 },
  { start: 9598, end: 9613, dist: 4 },
  { start: 9598, end: 9613, dist: 5 },
  { start: 9598, end: 9613, dist: 5 }
]

Note: the actual substring in the Haystack is "george \\ latimer"

Also, the start value seems to be slightly off (it starts in column 9611 according to my text editor).
Is there a reason for the multiple detections to the same substring, and the different values for dist returned?
Thanks!
