Configure matching settings for locate-source for helm-mini

Question

How can I configure helm-source-locate (for helm-mini) such that it matches like the following:

Type some tex it should match some_file.tex as well as b_some_other_file.tex.

Answer 1

Fuzzy matching (enabled for some commands but disabled by default) should do the trick:

(setq helm-locate-fuzzy-match t)
(setq helm-mode-fuzzy-match t)

and/or:

(setq helm-completion-in-region-fuzzy-match t)

Answer 2

One has to change the helm-locate command:

(setq helm-locate-command "locate %s -e -A --regex %s")

(See: https://github.com/emacs-helm/helm/issues/940)

Since I want spaces and regex, it is not a fuzzy search what I asked for.
