Memory Search Plus is an independent DeepSeek Harness Web plugin for local, cross-session full-text search. It maintains a rebuildable, storage-bounded SQLite FTS5 derivative; source conversations remain authoritative.
This repository is tagged with the dsh-plugin topic for discoverability.
origin=subagent) are not.detail=none, and a separate document table. User/Agent messages index up to 8 Ki characters; tool output indexes a balanced 4 Ki head/tail preview and is labelled as such in results.${DSH_HOME}/storages/memory-search/index.db. Settings can point it at another directory or .db file; DSH_MEMORY_SEARCH_DB does the same without the UI. Default logical budget is 1 GiB. At the budget only the oldest derived rows are evicted—never source conversations. Settings reports disk use, coverage start, and eviction count. No network calls or telemetry are used.| Scenario | Target |
|---|---|
| Local index write path, 1M synthetic messages | < 60 s |
| Query (mixed Chinese/English/phrase) | < 300 ms |
| Incremental update | only changed events are touched |
Measured numbers from the bundled benchmark (scripts/bench.mjs) are recorded in the QA output.
DSH_MEMORY_SEARCH_MAX_INDEX_MB=<MiB> changes the limit (64–16384 MiB).DSH_MEMORY_SEARCH_MAX_INDEX_MB=0 explicitly selects an unlimited index..db file). Saving moves the live index.db (and WAL sidecars) there and deletes the old files. The chosen location is stored at ${DSH_HOME}/storages/memory-search/location.json.DSH_MEMORY_SEARCH_DB=<absolute path> is used when there is no UI override.The index is a derivative cache. Eviction never modifies DSH session files; a manual rebuild rereads the source and converges to the configured budget again.
Requirements: DeepSeek Harness 0.1.1-rc.2 or later and its supported Node.js version (^22.19 || >=24).
Install the plugin into the Web profile, then restart Web (or your existing dsh-tunnel / gateway process, so the Host half reloads):
dsh plugin --profile web add github:the-thinker0/dsh-memory-search-plus
dsh web
Local development install from a clone of this repository:
dsh plugin --profile web add ./
The repository commits the required lib/ artifacts, so these installs do not ask pnpm to run a package build script.
Open the actual URL printed after dsh web: in the startup output (default http://127.0.0.1:3080).
DeepSeek Harness does not silently push plugin updates onto machines that already installed this package. A new GitHub release is not installed until the profile fetches it.
If you installed with github:the-thinker0/dsh-memory-search-plus, pull the latest commit and restart Web (or your existing dsh-tunnel / gateway):
dsh plugin --profile web add github:the-thinker0/dsh-memory-search-plus
dsh plugin forwards to pnpm in the profile directory, so dsh plugin --profile web update dsh-memory-search-plus also works when that subcommand is available. After the Host half changes, restart the process that loads plugins; a browser refresh is enough only for the Web client.
A file: / link: local checkout does not follow GitHub. Pull that clone yourself, then re-add or restart as you already do for development.
Optional: community tools such as dsh-market or dsh-update-copilot can check GitHub HEAD against the pinned lockfile commit and run the same dsh plugin add for you. They still require an explicit click; nothing is auto-installed in the background.
Remove the plugin with:
dsh plugin --profile web remove dsh-memory-search-plus
Note: the plugin registers
memory-searchas its Cordis plugin id; removing the package removes the whole plugin, including its index database (a prompt will confirm removal of the registered patch).
pnpm install
pnpm run check # typecheck + build (tsdown) + pack dry-run
Layout: the package is a Cordis Service plugin. src/index.ts is the Host half (SQLite FTS5 indexer + two-stage search API, exported as { name, inject, apply } via lib/index.js); src/client/ is the Web half (sidebar pill + results panel, delivered as lib/client.js wrapped in window.__ModuleLoader__.load(...)).
The host API contract — module interfaces (tokenize, extractSessionEventText, anchorKeyFor, SearchIndex, computeSpans/buildSnippet), RPC result shapes and the degradation guarantees — is specified as an executable acceptance contract in tests/README.md (see its QA test contract section). Unit tests live under tests/; the reproducible benchmark is scripts/bench.mjs (--impl lib/index.js measures the real implementation).
Everything is local: session events are read from local DSH storage into a bounded SQLite derivative. The index file stays on the machine you choose (default under DSH_HOME, or a path set in Settings / DSH_MEMORY_SEARCH_DB). The plugin registers no network calls, analytics, telemetry, or external CDN assets. SQLite/FTS secure deletion is enabled, and only the newest corrupt-index backup generation is retained.
v1.0.0. This is a community project, not an official DeepSeek release. Current compatibility target: DeepSeek Harness 0.1.1-rc.2.
