Session content search for the DeepSeek Harness sidebar — one-click toggle between title and content, with user / reply / tool filters
中文 · English
# dsh-switch-search
> Sidebar **session-search enhancement** for DSH web: adds a **"Search"** entry at the sidebar footer whose floating panel toggles between **title search ↔ content search**; content mode groups results **by session** (title + snippet) and filters by **user / reply / tool**.
A cordis client + host plugin assembled via the `dsh plugin` command and a bundle patch — no dsh source changes, no PR required.
## What it does
- **Title ↔ content toggle**: two ways to search from one entry — "Title" filters by session title / working-directory substring live; "Content" searches message bodies through DSH's built-in FTS5 full-text index.
- **Content grouped by session**: each content result is one row (session title + strongest snippet + type tag); clicking opens that session — no per-message flood.
- **Content-type filter**: filter chips at the top of content mode — **All / User / Reply / Tool**; `Tool` opens `tool/call` and `tool/result` events into the index, so you can search tool call arguments and results directly.
- **Index availability probe**: the host `search-status` endpoint checks whether the `sessionQuery` full-text index is enabled; when it is not, content mode shows one concrete setup instruction instead of a bare "content search unavailable".
- **General settings row**: Settings → General gains a **"Session Search"** row — enable toggle + default search mode (title/content), applied on write.
- **Jump to session**: clicking a result opens that session, landing on the context around the hit.
## UI preview
Entry at the sidebar footer and the floating panel layout:
```text
┌─ Sidebar ───────────────────────────────┐
│ ▸ Session search （sidebar.footer.action）
│ ┌─ Search panel (portalled) ──────────┐
│ │ [Title|Content] [🔍 Search…] │
│ │ [All|User|Reply|Tool] ← type filter │
│ │ ┌─ Results ─────────────────────┐ │
│ │ │ 📄 Session title one │ │
│ │ │ matching snippet… │ │
│ │ │ 📄 Session title two · tool │ │
│ │ │ bash -c "xxx" │ │
│ │ └──────────────────────────────┘ │
│ └─────────────────────────────────┘│
└──────────────────────────────────────────┘
```
## Underlying content search: the DSH FTS5 derived index
Content mode does not build its own database — it reuses DSH's **SQLite FTS5 derived index** (`session-query-sqlite`):
| Table | Description |
|---|---|
| `persisted_docs` (FTS5) | Full-text docs of persisted sessions (`text` searchable; `type/session_id/seq/...` as filter columns) |
| `temp.live_docs` (FTS5) | Full-text docs of the current process's live sessions |
| `persisted_sessions` / `live_sessions` | Session headers + `revision`/`fingerprint` (incremental rebuild keys) |
| `search_state` | Generation counter driving pagination-cursor invalidation |
- **Lazy index**: with `openAt: first-search` the index builds on the first search; each search does an **incremental reconcile** (rebuilds only changed sessions) — the first search on a large corpus is slower, later ones are fast.
- **Tool content is searchable**: `extraction.ts` explicitly feeds `tool/call` (name + arguments) and `tool/result` (result text) into the index — this is the data basis for the plugin's tool filter.
### ⚠️ Prerequisite: enable the full-text index
**The official DSH bundle ships with the full-text index disabled** (`session-query-sqlite` has `openAt: never`; see `deepseek-harness/packages/bundle/web-app/cordis.patch.yml`). To make content search work, override it in your profile's `cordis.patch.yml` or an overlay:
```yaml
- id: session-query-sqlite
config:
path: ':memory:' # or a durable absolute path (survives restarts)
openAt: first-search # or startup
```
Then restart DSH web. If you do not enable it, the plugin's content mode shows setup guidance; title mode is unaffected.
## Installation
```sh
# Option 1: install directly from GitHub (recommended) — lib/ is committed, no local build
dsh plugin --profile web add github:drscrewdriver/dsh-switch-search#release-v0.1.0 # stable
dsh plugin --profile web add github:drscrewdriver/dsh-switch-search#master # baseline
dsh plugin --profile web add github:drscrewdriver/dsh-switch-search#feat/type-filter-search # latest dev
# Option 2: assemble from a local path / source (see Development)
# Restart dsh web — required! A running instance does not hot-load the bundle layer
dsh web
# or use the bundled script
bash ~/.dsh/profiles/web/node_modules/dsh-switch-search/restart-dsh-web.sh
```
After install a **"Search"** button appears at the sidebar footer; Settings → General gains the **"Session Search"** settings row.
## Development
```sh
pnpm install # includes the @deepseek-ai client chain + tsdown/tsc
pnpm typecheck # tsc --noEmit
pnpm build # tsc (lib/types) + tsdown (lib/index.mjs + lib/client.js)
```
### Layout
```
src/
├── index.ts # host half (node): Config schema + installSettingsSection + routes
├── config.ts # pure shared config (enabled/defaultMode + namespace constant, schemastery-free for client)
└── client/
└── index.ts # browser half: sidebar.footer.action entry + floating panel + settings.general.item row
```
- **Host half**: registers the fenced HTTP route `/switch-search/api` (`list-sessions` / `content-search` / `search-status`), with a browser-trust fence identical to the DSH `/api` gateway (loopback Host or trustedHosts; cross-site refused).
- **Config pattern**: modeled on dsh-thinking-levels — the host registers the `switch-search` namespace through the `settings` service with a schemastery `Config`; the client mirrors/edits it with `defineStore` + `settingsScope.bind`; the shared pure module `src/config.ts` keeps schemastery out of the client bundle.
- **Build chain**: tsdown mirrors the harness `packages/client/tsdown.client.ts` semantics (`__ModuleLoader__.load` banner, platform externals table, bundle purity gate).
- **lib/ committed**: GitHub installs run off the committed build output (dsh does not run `prepare` on a git install); `.gitignore` does not exclude `lib/`.
## Branch map
| Branch | Purpose |
|---|---|
| `master` | Stable baseline (title ↔ content toggle, session grouping) |
| `feat/type-filter-search` | Development (content-type filter + settings index entry + availability probe) |
| `release-v0.1.0` | Stable installable version derived from the validated dev state, ships `lib/` |
## Relation to the official sidebar search
- The official sidebar search box lives in `sidebar.workspaces` (a single slot); an external plugin **cannot replace it**. This plugin adds a **separate entry** at the sidebar footer via `sidebar.footer.action`; the two coexist.
- The official content search hard-codes `user/message` + `assistant/message` in apiproxy; this plugin relaxes the filter through a `types` parameter to include `tool/call` + `tool/result`, enabling tool-level search.
## Compatibility and privacy
- Requires DeepSeek Harness with the web profile; all data goes through the built-in `sessionQuery` service (live-preferred corpus) — **no official source changes, no derived database**.
- Configuration lives only in the DSH settings namespace and browser panel state; it reads/upload nothing beyond session-search data.
- Host/client contract types are declared structurally in `src/*.ts` (the npm dsh client chain is incomplete) and mirror the harness sources at build-verification time.
