 - **Post** (`journal-post`): title, date, reading time, categories, author, featured image, body, previous and next links, and related posts. When the API returns no related posts (a post without a category), the latest posts are shown instead.
 - **Category** (`journal-category`): name, description and the category's rich HTML content above its posts. Categories are always requested with `include_empty=1`, so a category without posts still has a page. An unknown category answers 404, which makes the route safe as a root-level catch-all such as `/:category`.
 - **Tag** (`journal-tag`) and **author** (`journal-author`) pages. An author resolves by author slug, or by login once the author has a published post; a login URL sets the canonical to the slug URL.
+- **Search** (`journal-search`, opt-in): a results page for `?q=` and the `JournalSearchBox` header component with suggestions as the visitor types. Off until the app sets `journal.routes.search`. See [Search](#search).
 - **RSS**: `/rss.xml` proxies the API feed, and list and post pages link it in the head.
 - **SEO**: per-page title and description, Open Graph tags (`og:image` from the featured image, article times), canonical URLs that keep `?page=N`, robots and `sitemap.xml` through `@nuxtjs/seo`.
 - **HTML sanitizer**: post bodies and category content go through `sanitizeJournalHtml` before `v-html` and before they reach the SSR payload. It is [sanitize-html](https://github.com/apostrophecms/sanitize-html) with the Journal API's own allow-list: the usual content elements, `footer`, `class`, schema.org microdata, the `color`, `font-size`, `font-weight` and `text-align` inline styles, and `http`, `https`, `mailto` or relative URLs. Four rules keep the Journal Blog Editor's own markup, mirroring the API's policy: `data-embed` (`youtube`) and `data-id` (an 11-character video id) on `figure`, `alt` with any text on `img`, and an integer `start` on `ol`. Anything else (`script`, `style`, `iframe`, `svg`, forms, event-handler attributes, `javascript:` URLs in any spelling) is removed and the rest of the value is kept, so a post never renders blank because of one stray tag. Server and browser produce the same string, so hydration matches. See `docs/decisions/0001-sanitize-html.md`.

 - Why: nuxt-site-config publishes every `NUXT_SITE_*` variable in the page payload, so up to 0.5 a token set under `NUXT_SITE_CACHE_PURGE_TOKEN` appeared in every page as `cachePurgeToken`. From 0.6 the layer strips both keys from the site config even under the old names.
 - Rotate a token that was ever set under `NUXT_SITE_CACHE_PURGE_TOKEN`: earlier versions published it. Set the new value in the site's `NUXT_CACHE_PURGE_TOKEN` and in the backend's `site_cache.purge_token`, then restart both.
 
+## Search
+
+Search is off by default: an app that does not set `journal.routes.search` gets no search page, and `JournalSearchBox` renders nothing. To turn it on:
+
+```ts
+journal: { routes: { search: '/szukaj' } },
+```
+
+The Journal API answers `GET /posts?search=` from Typesense in relevance order when the backend has it on, and from SQL otherwise; the layer sends no `sort` with a search, so the API's order is kept. Terms under 3 characters are never sent: the API would ignore them.
+
+**Results page** (`journal-search`). Reads `?q=` and `?page=N`, renders the matches with `JournalPostList` and `JournalPagination` under a search form and a result count (plural forms through `Intl.PluralRules`: Polish one, few and many), and shows its own message for an empty term, a term under 3 characters and no results. It is fetched with `useAsyncData` on the server, so it works without JS. The title includes the term; the term is rendered as text everywhere.
+
+**Header box** (`<JournalSearchBox />`). An icon button opens a search input; once the term has 3 or more characters, a suggestion request (`GET /posts?search=…&fields=suggest&per_page=5`) goes out 250 ms after the last keystroke, and a newer term aborts the running request and drops its answer. Up to `limit` suggestions show the title, the excerpt and a small featured image, with the query words in `<mark>` ignoring case and diacritics ("grzybow" marks "grzybów"); the marking splits text and never inserts API HTML. Under them, "see all results" links to the search page with `q`. Enter opens the active suggestion, or the search page when none is active. The input is a WAI-ARIA combobox: ArrowDown and ArrowUp move through the options (`aria-activedescendant`), Escape closes the box and returns focus to the button, and a click outside closes it. A spinner shows after 300 ms, "no results" when nothing matched, and a quiet message when the request failed. Without JS the box is a plain GET form to the search page, always shown. Reopening selects the previous term.
+
+| Prop | Default | Meaning |
+|------|---------|---------|
+| `limit` | `5` | Suggestions shown |
+| `minLength` | `3` | Shortest term that sends a request |
+| `debounce` | `250` | Wait after the last keystroke, in ms |
+| `placeholder`, `buttonLabel`, `seeAllLabel`, `emptyLabel` | the `journal.search.*` strings | Text overrides |
+
+The `icon` slot replaces the magnifier. The root gets `journal-search--open` while open and `journal-search--enhanced` once mounted. The panel (`.journal-search__panel`) is inline next to the button, with the suggestions (`.journal-search__dropdown`) positioned below its left edge; an app makes it a full-width panel under its header, or anchors the suggestions on the right (`left: auto; right: 0`), in its own CSS.
+
+**Caching, robots and sitemap.** Nitro's route cache keys by path, so under an app rule such as `'/**': { swr: 300 }` every `?q=` would get the first query's cached page. The journal module therefore adds `{ cache: false, robots: 'noindex, follow' }` route rules for the search path and its locale-prefixed copies (`/pl/szukaj`), and excludes them from `sitemap.xml`. An app's own rule for the same path wins key by key. The search page is not route-cached: every search renders on request.
