Order search results with the same name by function arity

[daliboris]

When I search for sm:create-account function, results are sorted in the following order:

1. sm:create-account#4
2. sm:create-account#6
3. sm:create-account#3
4. sm:create-account#5

Describe the solution you'd like
For better orientation in function signatures, it is useful to sort functions with the same name according to arity:

1. sm:create-account#3
2. sm:create-account#4
3. sm:create-account#5
4. sm:create-account#6

Let me know if I can help with the development of this functionality.

here is the relevant line in the code

function-documentation/src/main/xar-resources/modules/app.xqm

Line 228 in 189880c

order by $function/xqdoc:name

[line-o]

sorting should then be something like

order by $function/xqdoc:name, xs:integer($function/xqdoc:arity)
