One Piece Card Game search syntax

The card search takes plain text and typed filters in one box — no mode toggle. Plain words search card names; anything with an operator becomes a filter. Anything the parser doesn't understand falls back to name search, so a query can never error.

General rules

field:value — operators are : = != < <= > >=. :means "has / contains".
Space means AND: c:red cost<=3. Use or and parentheses to group: (t:leader or t:character).
- negates: -c:red excludes red.
Quotes keep phrases together: o:"draw a card".
Paste a card code on its own — OP01-001 — and it searches codes as well as names. To match only a code, spell the field: code:OP01-001. A whole set is set:, not code:.
Colour-type fields compare as sets: : and >=mean "has all listed", = exactly, <= "only these" (fits-my-deck), != none of them. Single-letter codes combine where the game has them.

Fields

Field	Aliases	Matches	Operators	Example
`n`	`name`	text — `:` contains, `=` exact	`: = !=`	`n:value`
`t`	`type`	text — `:` contains, `=` exact	`: = !=`	`t:value`
`r`	`rarity`	text — `:` contains, `=` exact	`: = !=`	`r:value`
`s`	`set`	text — `:` contains, `=` exact	`: = !=`	`s:value`
`o`	`text`, `oracle`, `effect`	rules text (full-text search)	`: =`	`o:"draw a card"`
`owned`	—	cards already in your collection (requires signing in)	`: = !=`	`owned:yes`
`c`	`color`	colour set — see the set-membership rules above	`: = != < <= > >=`	`c:red`
`cost`	—	number	`: = != < <= > >=`	`cost<=3`
`pow`	`power`	number	`: = != < <= > >=`	`pow<=3`
`counter`	—	number	`: = != < <= > >=`	`counter<=3`
`life`	—	number	`: = != < <= > >=`	`life<=3`
`k`	`keyword`, `is`	list — `:` contains, `=` exact entry	`: = !=`	`k:value`
`tr`	`trait`	list — `:` contains, `=` exact entry	`: = !=`	`tr:value`
`attr`	`attribute`	text — `:` contains, `=` exact	`: = !=`	`attr:value`
`cn`	`code`, `number`, `collector`	printed card code, exact — `set-number`, or just the number	`: = !=`	`cn:OP01-001`
