Filter

There are different types of Filter

filterByXy - Xy are connected by AND, if multiple are given
filterByXyOr - Xy are connected by OR, if multiple are given
filterByXyExcluded - Xy found here, will exclude the object

Xy is a placeholder for the filters that exist like, filterByKeywords, filterByWeapons, filterByFactions, filterByAlchs etc.

Example

filterByKeywords has 2 keywords and they match.
filterByKeywordsOr has 5 keywords and at least one needs to match.
filterByKeywordsExcluded has 10 keywords and if one matches, the match will fail.

If one option missing, the rules still apply.
filterByKeywords has 2 keywords and they match.
filterByKeywordsExcluded has 10 keywords and if one matches, the match will fail.

filterByKeywords has 2 keywords and only ONE out of two matches. The match failed.
filterByKeywordsOr has 5 keywords and at least one matches.
filterByKeywordsExcluded has 10 keywords and none matches.

The operation will fail, because filterByKeywords failed to match all it's keywords, even when filterByKeywordsOr and filterByKeywordsExcluded passed.


You can also use any combination of Filters

Example for Armors from Fallout 4, it also applies to Skyrim

ArmorTypePower [KYWD:0004D8A1]

(bipedSlots are always accessed by index)
filterByBipedSlots=11 :filterByKeywordsExcluded=Fallout4.esm|0004D8A1

This will filter all armors that have bipedSlot 41 (index=11, [A] Torso) and don't have the keyword ArmorTypePower 


Filters work independent from each other. Which means that when the filterByWeapons has a match, filterByKeywords can also match the item.
If filterByWeapons has no match filterByKeywords still can have a match


If no Filter are set, all records will be accessed.

EXCEPTION: The player is always excluded from race or keyword filtering. If you want to patch the player, usefilterByNPCs:Skyrim.esm|7 and no other filter.
