Search Proxy is BYOS: Bring Your Own Search. It gives a site a first-party path for search while SuggestAPI performs retrieval and ranking. Use it when browser clients should call your own domain, when you need a stable public search URL, or when you want to apply controls before a request reaches SuggestAPI.

When to use it

  • expose search under your site domain without exposing a private server-side key
  • preserve an existing search URL while moving ranking and retrieval to SuggestAPI
  • centralize CORS, rate limiting, analytics, and cache policy at your edge
  • map a storefront or application route to one SuggestAPI index

Configuration

Create one proxy configuration for each public search surface. The exact controls are managed in the SuggestAPI app; use the following values when setting it up.

Setting Purpose Example
Public path The route callers use on your domain. /api/search
Upstream endpoint The SuggestAPI endpoint to proxy. /v1/autocomplete
Index mapping The fixed index, or the allowed mapping from request to index. products
Allowed methods Methods accepted by the proxy. Keep search surfaces read-only. GET
Authentication mode How the proxy authenticates to SuggestAPI. Keep private credentials at the proxy, not in browser code. server-side API key
Forwarded query fields The query parameters passed upstream. query, limit, filters, user_id
Cache policy Whether, where, and for how long successful responses are cached. cache anonymous GET searches
Origin policy Browser origins permitted to call the path. https://shop.example.com

Use a fixed index whenever possible. If you allow the caller to choose an index, explicitly allowlist its values; do not pass arbitrary index IDs through a public route.

Supported paths

Search Proxy is intended for read-only search traffic:

  • /v1/autocomplete for ranked search results
  • /v1/typeahead for fast prefix suggestions

Keep index administration, ingestion, exports, and other mutation routes off the public proxy. Those routes require trusted server-side access and should be called directly from your backend or the SuggestAPI app.

Authentication and headers

The proxy should inject a server-side SuggestAPI credential. Do not put a private key in JavaScript, page markup, or a mobile application bundle.

Pass only the headers your public contract needs. In particular:

  • use X-Bypass-Cache only for trusted diagnostics; do not allow untrusted clients to force uncached upstream work
  • treat user_id as an identifier subject to your privacy policy
  • return CORS headers only for approved browser origins
  • preserve a request ID in logs so an application request can be correlated with SuggestAPI diagnostics
