Notes

Zone-change search filters only consider end-to-end observable game state changes. Therefore, these filters ignore the Stack. For example, Cyclopean Mummy's Oracle card text reads: 'When Cyclopean Mummy dies, exile it.' This triggered ability gets interpreted as an end-to-end Battlefield to Exile zone change, although another effect in principle might steal Cyclopean Mummy from its owner's Graveyard (if, via the Stack, happening before resolution of mentioned triggered ability).

Search filters are mostly defined at ability category granularity (i.e. 'static', 'activated', 'triggered', 'spell', or sometimes more specifically 'characteristic-defining' ability, etc.). A single filter might refer to multiple ability categories, e.g. a triggered ability dynamically generating a static ability (like 'suspend' generating 'haste').

Conceptually related search filters are defined as mutually exclusive as possible, i.e. results from an ability category filter using Oracle card reminder text matching (e.g. the 'enters the battlefield' reminder text phrase in 'fabricate' triggered ability context) should not come up in related 'as generic card wording' filter results.

Most search filters are fine-grained instead of coarse-grained, keeping their embedded 'false positives' (i.e. wrong results) definitions from breaking search filter definition length limitations.

Also due to search filter definition length limitations, some filters have been split into several filter parts. (Empty filter part results have been removed from their respective card pools, just like empty 'regular filter' results.) Filter parts are identified by means of the following suffixes:
    '[part 1]', '[part 2]', etc.
    '[generic filter]', '[generic filter exceptions]', '[generic filter exceptions, part 1]', etc.

For practical reasons, only Standard-legal cards have been used to verify conceptual search filters framework completeness, new game mechanics continually extending this framework. Unfortunately, due to search filter definition length limitations, the following filters have not been implemented (awaiting Oracle card text templating improvements):
     [Battlefield presence]: permanents count, as generic card wording
     [Battlefield interaction]: damage to creatures, as generic card wording
     [life resource]: damage to players ('controller', 'him or her', 'opponent', 'player', 'you', ...), as generic card wording
     [zone change]: graveyard 'put', as generic card wording
     [zone change]: battlefield target based exiling, as generic card wording
     [zone change]: graveyard pick based exiling, as generic card wording.
Due to too many filter parts, the following filter has not been implemented:
     [characteristics]: Creature reference

Also, fractional Converted Mana Cost, power, and toughness (from the 'Un-Sets') filters have not been implemented.

Any residual 'false negatives' (i.e. missed results) risk is directly caused by Oracle card text pattern matching complexity, mostly found in 'as generic card wording' designated search filters. Their respective detailed specification/query links provide a means for concrete risk assessment.

The single unifying nature of the search filters framework (i.e. single filter definitions irrespective of card pool) implies that search filters within specific card pools might refer to extra glossary items unrelated to those card pools, e.g. unused older/newer keywords. However, all glossary items only associated to empty filter results within specific card pools have also been removed from those card pools' respective glossaries, avoiding further clutter.

All search filter results are sorted by converted mana cost (ascending).
