The Algolia crawler indexes production, so every hit URL is absolute (https://sourcegraph.com/docs/...). DocSearch rendered those verbatim, so selecting a result on a Vercel preview (or local dev) always jumped to prod. Pass a transformItems to DocSearch that strips the prod prefix and prepends NEXT_PUBLIC_DOCS_BASE_PATH, so hrefs resolve against the deployment being viewed: /docs/<path> in prod, /<path> on previews.

Problem
On a Vercel preview deployment (or local dev), searching for something, then clicking on a search result always takes you to
https://sourcegraph.com/docs/...instead of the matching page on the deployment you're viewing.Cause: the Algolia crawler indexes prod, so every hit's
urlis an absolute prod URL. The vendored DocSearch renders it verbatim inHit.tsx(<a href={hit.url}>) and returns it fromgetItemUrl(Enter-key navigation), so nothing ever makes it relative to the current origin.Fix
Pass a
transformItemstoDocSearchinsrc/components/search/Search.tsxthat rewriteshttps://sourcegraph.com/docs/<path>→${NEXT_PUBLIC_DOCS_BASE_PATH}/<path>.NEXT_PUBLIC_DOCS_BASE_PATHis already/docsin production and''elsewhere (seenext.config.js), so:/docs/batch-changes/view-batch-changes#viewing-batch-changes(same target as today)/batch-changes/view-batch-changes#viewing-batch-changes, resolved against the current origintransformItemsruns beforesaveRecentSearch, so recent/favorite searches persisted in localStorage get the rewritten URL too. URLs that don't start with the prod prefix are left untouched.Not changed
Verification
Tested on the preview deployment
