Bookmark Search Syntax
The full reference for regex:, in:, is:, count:, top:, date:, sg: and content: — and the :help cheat sheet.
Two ways to search
Every search box across X-Power Plus — Bookmarks, Current Tabs, History, Activity, Snapshots — understands the same query language, built on two layers:
- Plain keyword search — type any words, separated by spaces. Multiple words are combined with AND, matched as a substring against title and URL. This always works, on every plan.
- Syntax search — a recognized prefix followed by a colon, like
regex:oris:dead, for queries plain keywords can't express.
Syntax search is a Pro feature
All eight prefixes below require an active Pro license or the 30-day trial. On the Free plan, typing a syntax prefix shows an upgrade hint rather than silently falling back to a plain keyword search — so you always know which mode actually ran. Plain keyword search has no such limit on any plan. See Pricing, Trial & License Activation.
The eight prefixes
| Prefix | Meaning | Example | Available in |
|---|---|---|---|
regex: | Regular-expression match against title/URL. Used bare (just regex:) it matches everything. | regex:^https | Bookmarks, Activity, Current Tabs, History, Snapshots, dead-link results |
in: | Restrict the search to one folder. | in:work | Bookmarks main search |
is: | Status filter. Bookmarks: dead, alive, dup, opened, samehost, ip. Tabs: pinned, frozen. | is:dead | Bookmarks, Current Tabs |
count: | Filter by visit count — comparisons (>=, <=) or ranges. | count:>=10, count:10-99 | Activity, History |
top: | Show only the top N results by visit count. | top:20 | Activity, History |
date: | Time filter — units min/h/d/w/m. | date:7d, date:>1h | History |
sg: | Filter tabs by which Space they belong to. | sg:shopping | Current Tabs |
content: | Search inside page body text (requires Content Search enabled — see Content Search, Selection Search & Privacy Mode). | content:invoice | Current Tabs |
The :help cheat sheet
Type :help into any search box to see the exact set of prefixes valid for that box — not every prefix applies everywhere, so the cheat sheet always reflects the box you're actually in rather than the full list above.
Empty-result auto-reset
If a search comes back with nothing, the box automatically clears itself after a short delay so you're not left staring at an empty list from a query you've forgotten about:
Plain keyword search
Resets after 5 seconds by default (configurable, 2–60s).
Syntax search
Resets after 30 seconds by default (configurable, 5–300s) — longer, since syntax queries are usually more deliberate.
