In simple terms, distance is the number of characters that differ and ratio is the percentage of characters that differ. So, rocks and docks will have a distance of 1 and ratio of .8.
From Splunker Burch Simon:
"Ever wonder if it’s possible to search things that aren’t an exact match? What if you’re looking for “Google” in your data but still want to find matches for “Gogle” and “Googlle”? Well, you’re in luck because that’s exactly what the Levenshtein command does! Extend your SplunkFu by finding and filtering results based on how close of a match they are. Say goodbye to your binary world of equals and not equals. Say hello to Levenshtein!"
Added all option to get ratio and distance fields at the same time.
