Searching

Everything in the search bar is a space-separated list of terms: plain tags, negated tags, and key:value filters. All terms must match (AND) unless you use OR. Searches are case-insensitive.

A few rules that apply everywhere:

Images whose file is missing from disk are hidden unless the query contains missing:true.
Numeric and date filters accept comparisons (>, <, >=, <=, =) and ranges: X..Y (inclusive), ..Y, X...
A key:value term whose key is not a known filter is treated as a category-qualified tag search, so character:midna works even though character is not a filter keyword.
Type system: in the search bar to get this whole reference as a live dropdown, with drill-down hints per filter.

Basics

Query	Meaning
`tagname`	Images with this tag.
`-tagname`	Exclude images with this tag (`NOT tagname` also works).
`tagA tagB`	Images with both tags (AND).
`tagA OR tagB`	Images with either tag.
`red*`	Wildcard: tags starting with “red” (red_hair, red_eyes, …).
`*hair`	Tags ending in “hair”.
`hair`	Tags containing “hair”.

Tags and categories

Tags live in categories (general, character, artist, copyright, meta, rating, medium, person, year, plus any you create).

Query	Meaning
`character:tagname`	The tag “tagname” in the “character” category specifically.
`cat:character`	Images with any tag in the given category.
`tagged:true` / `tagged:false`	Images with at least one tag / with no tags.
`autotagged:true` / `autotagged:false`	Images with at least one auto-tag / with none.
`tagcount:>=10`	Number of tags on the image.
`rating:explicit`	Filter by rating: `general`, `sensitive`, `questionable`, `explicit`.

rating:X matches images whose highest rating is exactly X. An image carrying both general and explicit matches rating:explicit only. See Tags for how ratings and the SFW ceiling work.

File filters

Query	Meaning
`name:vacation`	Substring match against the filename only (folder names do not bleed in).
`size:>=10MB`	File size. Bare bytes or a unit suffix `B`/`KB`/`MB`/`GB`/`TB` (1024-based).
`mime:png`	File type: a bare bucket (`png`, `jpeg`, `webp`, `gif`, `mp4`, `webm`, `cbz`) or `image/...` / `video/...`. Comma-separate for a union.
`type:image` / `type:archive` / `type:animated`	File-type bucket: `image` = jpeg/png/webp, `archive` = cbz/zip, `animated` = gif/mp4/webm. Comma-separate for a union.
`width:>=1920`	Image width in pixels.
`height:<768`	Image height in pixels.
`ratio:>=1.5`	Aspect ratio (width divided by height).
`duration:>=30`	Video duration in seconds. Non-video rows never match.
`pages:>=100`	Page count of a comic archive. Non-archive rows count as 0 pages.
`hash:abcd...`	Exact match on the image’s SHA-256.
`id:123`	Exact match on the image id.
`missing:true`	Images whose file is missing from disk.

Folder, source, collection

Query	Meaning
`folder:path/to`	Images in that folder or any subfolder beneath it.
`folderonly:path/to`	Only images directly in that folder, no subfolders. Bare `folderonly:` means the gallery root alone.
`folder:"path with spaces"`	Quote paths that contain spaces.
`source:"source name"`	Images carrying that source. An image can have several sources; this matches any of them. Bare `source:` matches images with no source at all.
`collection:"collection name"`	Images filed under that collection. Bare `collection:` matches images in no collection; `collection:any` matches images in at least one.
`via:upload`	How the image was added: `ingest` (watcher or sync), `upload` (web form), `monloader` (pushed by a paired monloader), or any origin an API client supplied.

AI and generation metadata

See AI metadata for what monbooru extracts.

Query	Meaning
`ai:any`	Any AI-generated image (A1111 and/or ComfyUI metadata present).
`ai:a1111`	Generated with A1111/Forge (`ai:sd` is an alias).
`ai:comfyui`	Generated with ComfyUI.
`ai:none`	No detected generation metadata.
`generated:abcd1234abcd`	Other images sharing the same generation recipe; the hash is shown in the Generation data block on the detail page.
`prompt:cat`	Substring match across the SD or ComfyUI prompt.
`model:sdxl`	Substring match against the SD model or ComfyUI checkpoint name.
`sampler:dpm`	Substring match against the sampler name.
`seed:12345`	Exact seed.

State

Query	Meaning
`fav:true` / `fav:false`	Favorited / non-favorited.
`inbox:true` / `inbox:false`	In the inbox (untriaged) / archived.
`date:>2024-01-01`	Ingested after a date.
`date:2024-01..2024-06`	Ingested within a range.
`date:2024-03-15`	Ingested on an exact date.
`date:2024-03-15T19:23..2024-03-15T19:30`	Same, with hour (`THH`), minute (`THH:MM`) or second (`THH:MM:SS`) precision.

Relations and perceptual hash

See Relations for what these mean.

Query	Meaning
`phash:<16hex>`	Exact perceptual-hash match. There is a copy button on the detail page’s pHash row.
`phash:<16hex>~4`	Within Hamming distance 4 (near-duplicates). Distances 0..64 accepted.
`phash:` / `-phash:`	Has a perceptual hash / does not have one.
`relation:duplicate`	Image is in any duplicate group.
`relation:original`	Image is the chosen original of a duplicate group.
`relation:alternate`	Image is in any alternate group.
`relation:version`	Image is on a version chain (either side).
`relation:derivative`	Image is the derivative end of an edge.
`relation:source`	Image is the source side of at least one derivative edge.
`relation:collection`	Image belongs to a collection.
`relation:any` / `relation:none`	Has any declared relation / none. `any` includes collection membership.

Sort options

The sort select sits next to the search bar; the direction select next to it flips ascending/descending.

Sort	Meaning
Newest	By ingest date, newest first (the default).
File size	Largest first.
Collection order	Group by collection alphabetically, then by each image’s position in it. When the search pins a single `collection:`, results read in that collection’s own order.

Random order is its own button next to the search bar (shortcut R): it shuffles the results, stays stable across page turns, and reshuffles when clicked again. The heart button beside it (shortcut F) filters the current search to favorites.

Saved searches

To keep a query around, run it, then open the Actions chooser next to the search bar and pick Save search (only shown while the search bar is non-empty). Saved searches appear in the sidebar; click one to run it, or its x button to delete it. They are per gallery.
