[feature request] Rewrite "_vacuumIndex" in the way so it doesn't use a recursion technique

[vladimiry]

The recursion technique is not very well scalable so the "Maximum call stack size exceeded"-like error occurs on some datasets.

I agree that it should be fixed, I just haven't touched js for more than a year, so it is unlikely that I'll write code to fix this issue.
Another way to avoid this issue could be to use termFilter that trims suffix. Something like (term) => term.substring(0, 24)

Fair enough. Still would prefer the issue to remain open as maybe someone will make a PR one day. I just disabled the vacuuming call as that should be ok for my use case.
