Research ab* stack overflow patterns

[yonzarecki]

Just an idea, if we set the levenshtein distance metric to not include deletions, we can change ab to be ab with no cost, catching this use-case. However, using such metric can cause uncontrolled deletions (even resulting in empty strings) matching every trace to every other trace, which is problematic..

This idea can still be useful if done right.

From what I saw when looking at the traces #115 , not even one of the traces I saw was in this pattern. I'm inferring this pattern is not that common and as such is "nice-to-have" and not critical for this sprint. Closing..
