When I use helm fuzzy matching, call helm-M-x type elm I would like emacs-lisp-mode to pop up as a candidate. Instead I get
helm-M-x
helm-gid
helm-dash
helm-locate
...
I don't find this default fuzzy matching very helpful. How do you achieve more intuitive fuzzy matching?
Looking up how to change this, I found the package helm-fuzzier and it looked promising but after installing it didn't work (it seems a bit outdated).
I guess you would have to modify or change the helm-fuzzy rank scoring function. Per default, helm fuzzy sort will sort match candidates based on their scores as computed with helm-score-candidate-for-pattern.
Now, I don't think any sane algorithm should rank emacs-lisp-mode a better candidate match to the search term elm than the candidate helm-M-x. If you think about it, the pattern elm is continuous in helm, not so in emacs-lisp-mode.
If the pattern is not continuous, then it does make sense to choose the starting letters first. Try searching for em instead and you'll see emacs-lisp-mode as your first candidate.
The fuzzy algorithm is helpful, provided you let it be helpful on it's on way.
emacs-lisp-mode as the first candidate or even as a candidate in the visible portion of my minibuffer. I get emerge-file emacs-version emacs-init-time emacs-index-search.... I do get it as the fourth when I use ema. I respectfully disagree with your assertion that if the pattern is not contiguous, ... it does not make sense to choose the starting letter.... For me at least, I find choosing the starting letters first is a lot more useful than contiguous patterns most of the time, particularly because elisp doesn't have namespaces.

helm-top. I need to type helm-t find it as per helm's default fuzzy matching. In contrast using ivy-regex-fuzzy which uses a combination of contiguous and non-contiguous searching, when I type ht, I get helm-top as the first candidate. Thank you by the way showing me the function I need to modify to achieve this behavior.
