Title with more relevance in the sort criteria of the search result

The current sort criteria was written here:

Xavier

Here are the current sort criteria:

• Sort by date: Issuer, date from the yearlines, currency, denomination, ruler, reference number, series, title
• Sort by ruler: Issuer, ruler, currency, denomination, date from the yearlines, reference number, series, title
• Sort by value: Issuer, currency, denomination, date from the yearlines, ruler, reference number, series, title
• Sort by type: Issuer, type, currency, denomination, date from the yearlines, ruler, reference number, series, title

I assume they remain the same.

I see problems when objects have these fields with the same values.

For example, in this search result https://en.numista.com/catalogue/index.php?r=%22suerte+y+salud%22&st=all&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw= all objects have

• issuer = Spain,
• date = ND,
• currency = denomination = ruler = empty,
• reference number = only N# number

Sort by date, ruler, value, or reference

The result is the same:

• Sort by date
  https://en.numista.com/catalogue/index.php?r=%22suerte+y+salud%22&st=all&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=&o=y
  • The result is order by:
    Issuer, date from the yearlines, currency, denomination, ruler, reference number, series, title
  • but the fields with different value are:
    reference number, series, title
• Sort by ruler
  https://en.numista.com/catalogue/index.php?r=%22suerte+y+salud%22&st=all&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=&o=r
  • The result is order by:
    Issuer, ruler, currency, denomination, date from the yearlines, reference number, series, title
  • but the fields with different value are:
    reference number, series, title
• Sort by value
  https://en.numista.com/catalogue/index.php?r=%22suerte+y+salud%22&st=all&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=&o=v
  • The result is order by:
    Issuer, currency, denomination, date from the yearlines, ruler, reference number, series, title
  • but the fields with different value are:
    reference number, series, title
• Sort by reference

My suggestion

In any case, I think the title of the object should be take account before the reference number in the sort criteria:

• Sort by date: Issuer, date from the yearlines, currency, denomination, ruler, title, reference number, series
• Sort by ruler: Issuer, ruler, currency, denomination, date from the yearlines, title, reference number, series
• Sort by value: Issuer, currency, denomination, date from the yearlines, ruler, title, reference number, series
• Sort by type: Issuer, type, currency, denomination, date from the yearlines, ruler, title, reference number, series

In my example, the sort by date, ruler, or value have this fields with different value:

title, reference number, series

and the order should be:

• Spain
