URL: 
https://github.com/apache/activemq-artemis/pull/4730#issuecomment-1880529377

   > The design of the matching is to be hierarchical which is relatively easy 
to understand and configure with words separated by a delimiter and wildcards 
that represent one (i.e. * by default) or more (i.e. # by default) words.
   
   Partial words also would be hierarchical, I mean `*` would never match a 
delimiter.
   
   > Right now, `*` means **a single word**. If we start accepting "partial 
words" then what does `*` become? Is it a single word when used alone and then 
something else when used with a partial word? If the latter, is it any single 
_character_? Is it 0 or more of any character (e.g. as it might be in a regular 
expression)?
   
   My tentative was to implement the behavior similar to the `*` in the shells: 
matching zero or more characters but **not the delimiter** to respect the 
hierarchy.
   
   >Also, how do partial words compare to each other in a hierarchy where 
matches are ordered from general to specific? Would `ab*` be more specific than 
`a*` when matching `abc`? What about `a*c`? Is that even supported? Where do we 
draw the line?
   
   Good catch, I hadn't thought to this use case but if that would be supported 
then `a*c` would be more specific of `a*`
   
   > Furthermore, what do we do with `#`? Should we support partial matches 
with it? If so, what does that mean? If not, why not?
   
   Theoretically, `*` should be enough for any partial match use cases because 
`#` matches zero or more words.
   
   > The potential configurations start to expand very quickly and will no 
doubt add complication to the code, the test-suite, and the documentation.
   
   This is an important point from the development point of view, are you 
thinking to any specific cases?
   
   > If there's a bug here it's that undocumented behavior is allowed and 
somewhat functional leading folks to assume it's intentional. I'm not saying we 
should fix that necessarily, but we should at least consider it so we don't 
keep letting folks get confused.
   
   My tentative was to clarify this gray area without causing issues to users 
that are already using this **officially unsupported** behavior.
