Query language

Search your notes with Lumen's GitHub-style query language. Here's how it works:

  • A search query can contain any combination of qualifiers, which are key-value pairs separated by spaces. For example, tag:log date:2021-07-11 matches notes with the log tag AND the date 2021-07-11.
  • To exclude notes matching a qualifier, prefix the qualifier with a hyphen. For example, -tag:log matches notes that do not have the log tag.
  • To include multiple values in a qualifier, separate the values with commas. For example, tag:article,book matches notes with either the article OR book tag.
  • Qualifiers can also be used to filter notes based on numerical ranges. To do this, use one of the following operators before the qualifier value: >, <, >=, <=. For example, backlinks:>10 matches notes with more than 10 backlinks; date:>=2021-01-01 matches notes with a date on or after 2021-01-01.
  • Text outside of qualifiers is used to fuzzy search the note's title and body. For example, tag:recipe cookie matches notes with the recipe tag that also contain the word "cookie" in the title or body.
  • To search for a value that contains spaces, wrap the value in quotes. For example, genre:"science fiction" matches notes with genre: science fiction in their frontmatter.

Qualifiers

Key Example
id id:1652342106359 matches the note with ID 1652342106359.
tag tag:recipe matches notes with the recipe tag.
tags tags:>1 matches notes with more than one tag.
date date:2021-07-11 matches notes with the date 2021-07-11.
dates dates:>1 matches notes with more than one date.
link link:1652342106359 matches notes that link to the note with ID 1652342106359.
links links:>1 matches notes with more than one link.
backlink backlink:1652342106359 matches notes that are linked to by the note with ID 1652342106359.
backlinks backlinks:>1 matches notes with more than one backlink.
tasks tasks:>0 matches notes with at least one open task.
no no:tag matches notes without a tag. no can be used with any qualifier key or frontmatter key.
has has:tag matches notes with one or more tag. has can be used with any qualifier key or frontmatter key. has and -no are equivalent.

Unrecognized qualifier keys are assumed to be frontmatter keys. For example, read:true matches notes with read: true in their frontmatter.
