tl;dr: Matching without respect to order in
the target involves multiple separate matches.
___

What's usually called "flex" matching (Icicles
calls it "scatter") just matches bits of the
pattern you provide _in order_, one after the
other.  The matches are scattered throughout
the target, but they are _in order_ there.

To match multiple patterns without regard to
order in the target, you need to match the
patterns separately, each against the original
target or each against the result of previous
matching.

Icicles or library orderless.el provides such
behavior.

With Icicles, you can match a pattern (regexp,
fuzzy, flex, substring, whatever), and then you
can match another pattern ... etc.  Because the
component matches are separate the resulting
overall matches have those component matches in
any order.

Incremental search on that page does not give me: orderless.el - where
is it?

It's not one of my libraries.  I mentioned it because,
like Icicles "progressive completion", it lets you get
matches of multiple patterns without respect to order.

Googling "orderless.el" tells me it's here:

Thank you.

I was also researching bookmark handlers in bookmark.el in built-in
Emacs.

From: bookmark-alist
HANDLER is a function that provides the bookmark-jump behavior for a
specific kind of bookmark instead of the default `bookmark-default-handler'.
This is the case for Info bookmarks, for instance.  HANDLER must accept
a bookmark as its single argument.

I am following it inside as I may wish to use built-in bookmark
functions for storage into database that later may be expanded into
various different formats.
