Use when you would rather not operate Meilisearch and accept about 250 ms search latency from a managed service. When not to use it: Indexed text leaves your infrastructure: decide which fields may be sent before indexing production data. ## Compatibility | Line | Module | Status | Since | Receipt | In isolation (empty preset) | |---|---|---|---|---|---| | 0.8 (0.8.0) | 0.1.1 | untested | - | - | - | | 0.9 (0.9.0) | 0.1.1 | verified | 2026-10-29 | https://modules.openmercato.com/r/r_20261029_71db7d0f3eca | - | | next (0.10.1-develop.7701.1.87b1ad4224) | 0.1.1 | untested | - | - | - | Built for 0.6 (peers >=0.6.0 <0.7.0).

A peer of the built-in Meilisearch driver in `@open-mercato/search`, implementing the same interface. Drop it in and `SearchService` fuses it with the `vector` and `tokens` strategies exactly as before. --- ## Read this first ### It replaces the search *service*, not the search *architecture* Open Mercato's search is three strategies fused with Reciprocal Rank Fusion: `fulltext` (Meilisearch), `vector` (pgvector/Chroma/Qdrant + an embedding provider), and `tokens` (a Postgres hash index that always works). This package supplies a second `fulltext` driver. Everything else is untouched, and `tokens` remains the fallback when Cloudflare is unreachable. The practical trade: you stop operating a Meilisearch container, and you accept ~250ms search latency instead of single-digit milliseconds. ### Backend list views are NOT affected Despite what you might assume, list-view `q` filtering does not go through `SearchService` — it joins `search_tokens` directly inside `QueryEngine`. Installing this changes **Cmd+K global search, `/api/search`, and the AI assistant's MCP search tool**. Nothing else. That is what makes it low-risk and trivially reversible. ### Your data goes to a managed service Meilisearch was a container you controlled. Cloudflare AI Search is managed and must hold readable text in order to embed it. This driver honours `fieldPolicy.excluded` / `fieldPolicy.hashOnly` and, with `SEARCH_EXCLUDE_ENCRYPTED_FIELDS=true`, the tenant encryption map — so encrypted fields stay searchable only via the `tokens` strategy, which hashes rather than storing plaintext. **Decide this before indexing production data.** It is a deployment decision the package cannot make for you. ### Cloudflare AI Search is in open beta, and we found a data leak in it See [Cross-tenant safety](#cross-tenant-safety). It is handled, but you should understand it before trusting the product with multi-tenant data. --- ## Install ```bash yarn add @northbound-run/search-cloudflare ``` Peer dependencies: `@open-mercato/search` and `@open-mercato/shared` (0.6.x). ### 1. Provision the instance Custom metadata fields must exist **before** any upload — Cloudflare silently drops undeclared fields, which would produce hits that cannot be mapped back to an Open Mercato entity. ```bash npx wrangler ai-search create my-instance \ --type builtin \ --hybrid-search \ --custom-metadata entity:text \ --custom-metadata org:text ``` `--hybrid-search` sets `index_method` to `{vector: true, keyword: true}`. Vector-only is the default and misses exact identifiers like `PO-10432`. ### 2. API token Needs **Account → AI Search:Edit** and **AI Search:Run**. A `wrangler login` OAuth token already carries both. ### 3. Environment ```bash CF_AI_SEARCH_ACCOUNT_ID= # npx wrangler whoami CF_AI_SEARCH_API_TOKEN= CF_AI_SEARCH_INSTANCE=my-instance # Optional CF_AI_SEARCH_NAMESPACE= # default namespace when unset CF_AI_SEARCH_RETRIEVAL_TYPE=hybrid # vector | keyword | hybrid CF_AI_SEARCH_MATCH_THRESHOLD=0.3 # Cloudflare default is 0.4 ``` ### 4. Enable the module ```ts // src/modules.ts { id: 'search_cloudflare', from: '@northbound-run/search-cloudflare' }, ``` Then `yarn generate`. That is the whole integration — no app `src/di.ts` wiring. The module ships no entities, migrations, routes or UI: a `di.ts` that registers the driver, and the `doctor` CLI. It declares `requires: ['search']`. **Registration has to live in a module `di.ts`, not the app's.** Open Mercato reaches app-level DI through `await import('@/di')` — a bundler-only path alias that throws `ERR_MODULE_NOT_FOUND` under raw Node into a bare `catch {}`.
