|
||||
|
||||
Paperless also offers advanced search syntax if you want to drill down further.
|
||||
|
||||
Matching documents with logical expressions:
|
||||
#### Combining terms
|
||||
|
||||
```
|
||||
shopname AND (product1 OR product2)
|
||||
invoice NOT draft
|
||||
"quick brown fox"
|
||||
```
|
||||
|
||||
Matching specific tags, correspondents or types:
|
||||
- `AND`, `OR` and `NOT` must be written in capitals. Parentheses group terms.
|
||||
- Terms with no operator between them are combined with `AND`.
|
||||
- Quotes match an exact phrase, with the words in that order.
|
||||
|
||||
!!! warning
|
||||
|
||||
A leading `-` does **not** exclude a term. `invoice -secret` finds documents containing both words. Use `invoice NOT secret` instead.
|
||||
|
||||
#### Searching by field
|
||||
|
||||
Put a field name and a colon in front of a value to search only that field:
|
||||
|
||||
```
|
||||
type:invoice tag:unpaid
|
||||
correspondent:university certificate
|
||||
correspondent:"acme corp"
|
||||
tag:bills,unpaid
|
||||
asn:[50 to 150]
|
||||
checksum:9f86d081*
|
||||
```
|
||||
|
||||
Matching dates:
|
||||
| Field | Searches |
|
||||
| ------------------------- | ---------------------------------------- |
|
||||
| `title` | Title |
|
||||
| `content` | Text content |
|
||||
| `correspondent` | Correspondent |
|
||||
| `document_type` or `type` | Document type |
|
||||
| `storage_path` or `path` | Storage path |
|
||||
| `tag` | Tags |
|
||||
| `original_filename` | File name the document was consumed with |
|
||||
| `asn` | Archive serial number |
|
||||
| `page_count` | Number of pages |
|
||||
| `num_notes` | Number of notes |
|
||||
| `checksum` | Checksum of the original file |
|
||||
| `created` | Created date |
|
||||
| `added` | When the document was added to paperless |
|
||||
| `modified` | When the document was last modified |
|
||||
|
||||
- A field applies only to the word right after it. Quote multi-word values: `correspondent:"acme corp"`.
|
||||
- A comma-separated `tag` list requires every listed tag, so `tag:bills,unpaid` only matches documents tagged with both.
|
||||
- `asn`, `page_count` and `num_notes` are numbers. They accept ranges like `asn:[50 to 150]`, but not wildcards.
|
||||
- `checksum` only matches the complete checksum, in lowercase. To search by its first few characters, add a wildcard: `checksum:9f86d081*`.
|
||||
- `created`, `added` and `modified` take the values described in [Searching by date](#searching-by-date).
|
||||
- Custom fields and notes have their own syntax, described [below](#searching-custom-fields).
|
||||
|
||||
#### Wildcards
|
||||
|
||||
```
|
||||
invoice*
|
||||
title:Invoice*
|
||||
20[12]?
|
||||
20[!0]?
|
||||
```
|
||||
|
||||
- `*` matches any number of characters, and `?` matches exactly one.
|
||||
- `[...]` matches one character from a set or range, and `[!...]` matches one character not in it. `20[12]?` matches 2010 to 2029.
|
||||
- Brackets only act as a wildcard when the value also contains a `*` or `?`. Otherwise they are searched as ordinary text. The exception is a single-character range such as `title:200[1-9]`, which is rejected with an error. Add a wildcard to use it as a pattern: `title:200[1-9]*`.
|
||||
|
||||
!!! note
|
||||
|
||||
When a [stemmer is available](configuration.md#PAPERLESS_SEARCH_LANGUAGE) for your search language, words are indexed by their stem, so `copy*` also finds "copies". A prefix that runs past the stem can find nothing: `universit*` misses "university", which is stored as `univers`. If a wildcard finds nothing, try a shorter prefix, such as `univers*`.
|
||||
|
||||
#### Searching by date
|
||||
|
||||
```
|
||||
created:[2005 to 2009]
|
||||
added:yesterday
|
||||
modified:today
|
||||
modified:"previous month"
|
||||
created:[2005 to 2009]
|
||||
added:[-1 week to now]
|
||||
```
|
||||
|
||||
Matching inexact words:
|
||||
These keywords each cover a whole period, and work with or without quotes: `today`, `yesterday`, `tomorrow`, `previous week`, `this month`, `previous month`, `previous quarter`, `this year`, `previous year`.
|
||||
|
||||
```
|
||||
produ*name
|
||||
```
|
||||
Other supported forms:
|
||||
|
||||
Matching natural date keywords:
|
||||
| Example | Matches | Quotes |
|
||||
| ------------------------------------------------------- | ------------------------------ | -------- |
|
||||
| `created:2005`, `created:2005-01`, `created:2005-03-04` | That year, month or day | Optional |
|
||||
| `added:january` | That month in the current year | Optional |
|
||||
| `added:"next monday"`, `added:"last monday"` | That day | Required |
|
||||
| `added:"12 december 2019"` | That day | Required |

||||

||||
modified:yesterday
|
||||
created:"previous week"
|
||||
added:"previous month"
|
||||
modified:"this year"
|
||||
```
|
||||
Ranges take two bounds in square brackets, for example `created:[2005 to 2009]`. A bound can be any of the forms above, or a relative time like `-1 week`, `now-7d` or `now`. Bounds don't need quotes. If you do quote one, use single quotes (`added:['-1 week' to now]`), because double quotes are rejected.
|
||||
|
||||
Supported date keywords: `today`, `yesterday`, `previous week`,
|
||||
`this month`, `previous month`, `this year`, `previous year`,
|
||||
`previous quarter`.
|
||||
!!! warning
|
||||
|
||||
`now`, `noon`, `midnight` and relative times like `-1 week` only work as range bounds. On their own they mean a single instant, so `added:"-1 week"` finds nothing. Use `added:[-1 week to now]` instead. A bare weekday (`monday`) and spellings like `3 days ago` or `this week` are not supported at all.
