Regex Search
Section titled “Regex Search”Each keyword in the filter panel has a Regex toggle. When enabled, the keyword is treated as a regular expression and matched against the filename (basename only, not the full path).
By default, regex searches are case-insensitive. Toggle Case Sensitive alongside Regex for exact case matching. Invalid regular expressions produce no results without showing an error.
| Keyword (Regex enabled) | Matches |
|---|---|
\d{4}-\d{2}-\d{2} | 2024-01-15_report.pdf, 2023-12-01_notes.txt |
config\.[a-z]+ | config.yml, config.json, config.yaml |
IMG_\d{4} (+ Case Sensitive) | IMG_2024.jpg only, not img_2024.jpg |
[Ff]oo\.[a-z]{3} | foo.txt, Foo.jpg |
\.bak$ | document.bak (note $ anchors to end) |
Path Search (Slash Search)
Section titled “Path Search (Slash Search)”When a keyword contains /, Liuer treats it as a path pattern and matches against the full file path instead of just the filename. This enables searching by directory structure.
| Input | Behavior | Matches |
|---|---|---|
src/comp | src appears somewhere in the path, last segment starts with comp | /project/src/components/Button.tsx |
/usr/bin | First segment exactly usr, last segment starts with bin | /usr/bin/python3 |
project/docs/ | project appears somewhere, last segment is exactly docs | /work/project/docs/ |
/Users/me/docs/ | Exact path prefix — matches files under this directory | /Users/me/docs/report.pdf |
docs/report.pdf | docs appears somewhere, last segment starts with report.pdf | /project/docs/report.pdf, /backup/docs/report-draft.pdf |
/etc | Starts with etc from root | /etc/hosts, /etc/nginx/nginx.conf |
config/ | config appears somewhere, last segment is exactly config (directory name) | /project/config/default.json |
Special Path Operators
Section titled “Special Path Operators”| Symbol | Meaning | Example | Matches |
|---|---|---|---|
** | Matches any directory depth | src/**/test | /src/a/b/c/test.js |
* | Matches exactly one directory level | backup/*/data | /backup/2024/data.db, not /backup/2024/01/data.db |
Multiple Path Keywords
Section titled “Multiple Path Keywords”You can combine multiple path patterns with boolean conditions (All Match / Any Match / Exclude). For example, use docs/ (All Match) plus draft (Exclude) to find files in docs directories without the word “draft”.
