Conflict Checking Multiply-Divided Field-Only Armory

A couple of years ago, I posted about a technique I picked up from Marie de Blois that allows conflict-checking two- and four-part field-only armory with the O&A complex search form.

It entails running a search for the line type, plus each of the tinctures, and for the tinctures together in reverse order, and the codes for field-only and peripheral-only.

So, to filter the O&A for possible conflicts with “Per fess argent and sable” you could search for:

  • PFESS:pl
  • PFESS:argent
  • PFESS:~and sable
  • PFESS:sable:~and argent
  • FO — give this line a weight of 2
  • PO

Any results that appear with a score of 4 or higher are a potential conflict.

It turns out that the same approach can also be used for fields divided into more than four parts, but the coding for the tinctures requires a slightly different approach.

To filter the O&A for possible conflicts with “Barry wavy Or and gules” you could search for:

  • FIELD DIV.-BARRY:wavy
  • FIELD DIV.-BARRY:or
  • FIELD DIV.-BARRY:~and or
  • FIELD DIV.-BARRY:gules
  • FIELD DIV.-BARRY:~and gules
  • FO — give this line a weight of 2
  • PO

Any results that appear with a score of 4 or higher are a potential conflict.

The extra tincture lines are there to handle cases in which a change of one tincture causes the other to be coded differently.

Because tinctures in multiple-part divisions are always coded in alphabetical order, “barry wavy or and gules” and “barry wavy gules and or” will both be encoded in the database as “FIELD DIV.-BARRY:gules:~and or”.

However, we also want our search to find “barry wavy argent and gules”, which would be a conflict as it has only one DC for changing the tincture of half the field — and that armory would be encoded as “FIELD DIV.-BARRY:argent:~and gules”.

Therefore our search needs to include both “:gules” and “~and gules” to ensure that we’ll match the tincture in either position.

Some of these search terms will never match anything and can be excluded — because argent is the first tincture alphabetically, we’ll never have a multi-part field coded as “~and argent”, and similarly because vert is last alphabetically, we’ll never see it appear in this context as “vert” — but they do no harm and are safe to include for purposes of consistency.
