Search syntax

The Browse search box, saved searches, custom study sessions (search kind) and insight links use Anki’s search syntax. The parser and SQL compiler are in crates/loci-core/src/search/.

Combining terms

You type	Finds
`dog cat`	notes containing both dog and cat (AND is implicit)
`dog and cat`	the same; `and` is optional
`dog or cat`	either word
`dog (cat or mouse)`	dog and either cat or mouse
`-cat`	notes without cat
`-(cat or mouse)`	notes with neither

and binds tighter than or, as in Anki: a b or c means (a and b) or c. Operators are case-insensitive.

Text

You type	Finds
`dog`	dog anywhere in the note’s text (HTML removed), also inside doggy
`"a dog"`	the exact phrase a dog; cloze markup is read as its text, so `"Paris is in France"` finds `{{c1::Paris}} is in {{c2::France::country}}`
`d*g`	`` matches any run of characters: dg, dog, dung*
`d_g`	`_` matches one character: dog, dig
`w:dog`	dog as a whole word (not doggy); `w:dog` matches words starting with dog*
`nc:uber`	ignores accents and other combining marks: matches über
`re:(?i)^colou?r`	a regular expression on the raw field HTML of any field
`sc:the cat`	text inside cloze deletions counts (`{{c1::cat}}` matches the cat)
`\*`, `\_`, `\"`, `\\`, `\:`, `$`, `$`, `\-`	the literal character

Plain text searches are case-insensitive. Terms of three characters or more use the full-text index (fast, case-insensitive in every script, including Arabic and CJK); shorter terms and terms with wildcards use a scan that folds case for ASCII letters only, as Anki does.

Fields

You type	Finds
`front:dog`	the field named Front is exactly dog
`front:dog`	Front contains dog
`front:`	Front is empty
`fr*:dog`	any field whose name starts with fr is exactly dog
`front:re:^d.g$`	regular expression on Front
`front:nc:uber`	Front equals uber, ignoring accents

Field searches match the field’s HTML, case-insensitively, one field at a time.

Decks, note types, cards, tags

You type	Finds
`deck:Languages`	cards in Languages and all its subdecks
`"deck:Languages::Arabic Verbs"`	quote names with spaces
`deck:Lang*`	decks matching a wildcard
`deck:current`	the deck you are studying or browsing from
`-deck:Languages::Arabic::*`	excludes the subdecks of Arabic (not Arabic itself)
`deck:*`	every card
`deck:filtered`	cards still in a filtered deck (none after import: Loci returns them home)
`preset:Standard`	cards in decks that use the Standard preset
`note:Basic`	notes of the note type Basic (wildcards allowed)
`card:1`	the first card type of each note (cloze: `card:3` is cloze 3)
`card:Reverse`	cards of the template named Reverse
`tag:verb`	notes tagged verb or any child tag (verb::irregular)
`tag:verb*`	tags starting with verb
`tag:none`	notes without tags
`tag:re:^ar.*s$`	tags matching a regular expression

Card state

You type	Finds
`is:due`	reviews and day-learning cards due today or earlier, and learning cards due now
`is:new`	new cards
`is:learn`	cards in (re)learning
`is:review`	review cards, including ones relearning after a lapse
`is:suspended`	suspended cards
`is:buried`	buried cards; `is:buried-sibling` and `is:buried-manually` split them
`flag:1`	red flag (2 orange, 3 green, 4 blue, 5 pink, 6 turquoise, 7 purple; `flag:0` none)
`tag:leech`	cards the scheduler marked as struggling

Properties

prop: compares a number with <, >, <=, >=, = or !=.

You type	Finds
`prop:ivl>=30`	interval of at least 30 days
`prop:due=1`	due tomorrow; `prop:due<0` overdue; `prop:due<=2` within two days
`prop:reps>10`, `prop:lapses>=8`	answered more than 10 times; lapsed 8 times or more
`prop:ease<2.0`	SM-2 ease under 200%
`prop:pos<=100`	new cards at position 100 or earlier
`prop:r<0.9`	FSRS retrievability (chance of recall now) below 90%, for every card with a memory state whatever its queue (review, learning, relearning, suspended, buried); days since the last review come from the card’s last-review time, else its due day, else its latest answer
`prop:s>90`	FSRS stability over 90 days
`prop:d>0.8`	FSRS difficulty above 80% (0–1 scale)
`prop:rated=-1`	answered yesterday; `prop:resched>-7` rescheduled in the last week
`prop:cdn:key>5`, `prop:cds:key=value`	custom data written by Anki add-ons
`has-cd:key`	cards that have that custom data key

Time

Days count back from the start of today (the day starts at the rollover hour, 4 am by default).

You type	Finds
`rated:1`	answered today; `rated:7` in the last week
`rated:7:1`	answered Again in the last week (`:2` Hard, `:3` Good, `:4` Easy)
`added:1`	cards added today
`edited:3`	notes edited in the last three days
`introduced:30`	cards first studied in the last 30 days
`resched:7`	cards rescheduled by hand (set due date, reset) in the last week

Identifiers

You type	Finds
`nid:1700000000000`	a note by id; several: `nid:1,2,3`
`cid:…`, `mid:…`, `did:…`	cards, note types, decks by id
`dupe:1700000000000,dog`	notes of that note type whose first field is dog

Examples

Struggling cards in one deck: "deck:Medicine::Anatomy" (tag:leech or prop:lapses>=8)
What is at risk today: is:due prop:r<0.8
New Arabic verbs: deck:Languages::Arabic::Verbs is:new
Notes you edited this week that contain an image: edited:7 re:<img
Cards you forgot yesterday: rated:2:1 -rated:1

Differences from Anki

Field searches and re: see the field’s HTML; plain text searches see the text without HTML. This is also Anki’s behaviour. Unlike Anki, plain text searches also see cloze deletions as the text they reveal (markers and hints removed), so a phrase can span a cloze boundary; search the markup itself with re: or a field search (text:*c1::*).
prop:r covers learning and relearning cards that have a memory state, not only review cards.
Filtered decks are not kept as decks in Loci, so deck:filtered normally finds nothing.
Searches that need a custom SQL function in Anki (fields, re:, nc:, w:, sc:, wildcard tags, dupe:) are evaluated in two steps: SQL narrows the candidates, then an exact check runs on each. The results are the same; very broad regular expressions on huge collections are slower.
