break(theme-search-algolia)!: upgrade to DocSearch v5 (AI-assisted) - #12406
Upgrades @docsearch/react from v4 to v5 and removes the DocSearch v3
compatibility layer that was carried during the v3/v4 transition period.
DocSearch v5 drops the old v3 APIs and introduces multi-index search and
Agent Studio-based Ask AI, neither of which can be expressed with the previous
single-index (indexName + top-level searchParameters) configuration. This PR
migrates the theme config surface accordingly.
This is the first PR in a stack. Documentation updates (search.mdx) will
follow in a separate stacked PR.
What changed
Bump @docsearch/react to ^5.0.4 (+ lockfile)
Add an algolia.indices array option (accepts string or {name, searchParameters} entries)
Load the search vs. Ask AI modal via dedicated dynamic entry points
(@docsearch/react/modal / @docsearch/react/askaiModal)
Migrate Ask AI to Agent Studio: assistantId → agentId, per-index searchParameters, and new memory / promptSuggestions options
Convert contextual facetFilters into Agent Studio filters strings
(new facetFiltersToFilterString / mergeFilters utilities)
Remove v3 version detection, webpack module aliases, ambient module
declarations, and the ensureAskAISupported guard
Refresh SearchTranslations for v5 labels
Breaking changes
Who does this affect: all sites using @docusaurus/theme-search-algolia
How to migrate:
Rename Ask AI assistantId → agentId
Ensure @docsearch/react v5 is installed
Why make this breaking change: DocSearch v5 removes v3 APIs and adds
multi-index + Agent Studio Ask AI, which the old single-index config cannot express
Severity: high reach (every Algolia search user) × low-to-medium effort
(mostly a config rename)

break(theme-search-algolia)!: upgrade to DocSearch v5 (AI-assisted)
Sep 18, 2026
Based on this section of our docs, I believe this is correct. The test cases here don't do a good job of portraying what information is being used imo.
To my understanding, mergeFacetFilters is combining 2 different sources of facets into a flat list. The root level of the built list are all inclusive, and params inside of nested arrays are exclusive. So this test case is stating that the output should be:
'f1' AND 'f2' AND 'f3' AND 'f4' which I believe is correct based on the input. Here's a better example that illustrates it better I think:

I agree, it is quite gross. I know @dylantientcheu mentioned previously that our other libraries team were working on something so I'll check with them.
If those plans changed for some reason, we can move this to an exposed utility in the DS repo itself.

Actually, this is all due to this comment, I'm going to also see about just having Agent Studio support facet filters which eliminates us having to convert facets to filters in the first place.
The reason will be displayed to describe this comment to others. Learn more.
Ask AI as an API service has been migrated into our Agent Studio service. It offers the same functionality, BYOK, search tool, etc; but adds a lot more features. For DocSearch it's still free (outside of the BYOK costs), and we have a migration wizard to convert an Ask AI assistant to an Agent Studio agent.
v5 does remove support for the Ask AI API, and only communicates with Agent Studio. We have a migration guide on our docs that walks through it better.
…ndices config (AI-assisted)
Upgrade @docsearch/react from v4 to v5 and drop the DocSearch v3
compatibility layer that was carried during the v3/v4 transition.
Changes:
- Bump @docsearch/react to ^5.0.4 and update the lockfile
- Replace `algolia.indexName` + top-level `searchParameters` with an
`algolia.indices` array (string or {name, searchParameters} entries)
- Load the search vs. Ask AI modal via dedicated dynamic entry points
- Migrate Ask AI to Agent Studio: `assistantId` -> `agentId`, per-index
`searchParameters`, and add `memory` / `promptSuggestions` options
- Convert contextual `facetFilters` into Agent Studio `filters` strings
(new facetFiltersToFilterString / mergeFilters utils)
- Remove v3 version detection, module aliases, ambient declarations, and
the ensureAskAISupported guard
- Refresh SearchTranslations for v5 labels and update tests
- Migrate website dogfooding configs to `indices` and adjust DocSearch CSS
BREAKING CHANGE: `algolia.indexName` and top-level `algolia.searchParameters`
are removed in favor of `algolia.indices`. Ask AI now uses `agentId` instead
of `assistantId`. DocSearch v3 is no longer supported.
- Who does this affect: all sites using @docusaurus/theme-search-algolia
- How to migrate: replace `indexName: 'x'` with `indices: ['x']`; move
`searchParameters` into the relevant index entry; rename Ask AI
`assistantId` to `agentId`; ensure `@docsearch/react` v5 is installed
- Why make this breaking change: DocSearch v5 drops v3 APIs and introduces
multi-index + Agent Studio Ask AI, which cannot be expressed with the old
single-index config
- Severity: high reach (every Algolia search user) x low-to-medium effort
(mostly a config rename)
- Correct lint script typo lint:SPELLING -> lint:spelling
- Fix "noisey" -> "noisy" typo in webpack warning comment
- Add "askai" to project-words.txt and cSpell:ignore IMYF in config
- Temporarily disable translation-consistency test (it.todo); translations
are deferred to a follow-up PR to keep this PR small
- The website no longer requires @docsearch/react since its config stopped
reading the DocSearch version: remove it and search-insights, only kept to
satisfy its peer dependency
- Don't export facetFilterToFilterClause, only used internally
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Ask AI search parameters now pass contextual and user facet filters
through `facetFilters` instead of converting them to an Agent Studio
`filters` string. This drops the filter grammar conversion in utils.ts.
Index normalization moves to useNormalizeIndices.ts with tests, and
useAlgoliaAskAi tests are added. Vitest gets an alias for
@theme/SearchTranslations so the search client resolves it in tests.

Walkthrough
The Algolia search theme now supports DocSearch v5, multiple indices, and expanded Ask AI configuration. It normalizes contextual facet filters for search and Ask AI, selects the corresponding modal, and updates search translations across locales.
Configuration accepts string or object indices, per-index search parameters, facets, and expanded Ask AI settings. Legacy indexName input normalizes to a single indices entry; conflicting index forms are rejected.
The new helpers normalize indices and merge contextual facet filters with configured filters. Ask AI search parameters are built per index, and tests cover filter preservation, hook state, and nested facet groups.

SearchBar selects and loads the search or Ask AI modal and passes normalized indices. SearchPage uses the first configured index, whether it is a string or an object.
The DocSearch version checks, v3 webpack aliases, and removed ambient declarations are deleted. The workspace catalog uses @docsearch/react^5.1.1; the website removes direct DocSearch and search-insights dependencies. The website Ask AI config uses agentId.

The theme adds DocSearch AI translation entries and adopts updated search-control and footer keys. Locale files update corresponding keys; the locale equality test is marked as TODO.

When Ask AI is configured, modalKind is always 'askai'. If the Ask AI chunk import rejects, openModal never calls setIsOpen(true). The modal stays closed, and the search-only modal is never loaded. The button's onFocus, onMouseOver, and onTouchStart preloads also reject without a handler.
🐛 Possible fix direction
No exact diff is proposed. A safe fallback would need to change modalKind and load the search modal, which this review did not establish.

Handle Ask AI chunk-load failures in the `openModal` flow and the button’s
`onFocus`, `onMouseOver`, and `onTouchStart` preload handlers so rejections are
handled and opening does not silently remain stuck. Establish the supported
failure behavior before implementing a fallback; if search-modal fallback is
supported, update `modalKind` and load that modal consistently rather than
assuming it is safe.

Type contextualSearch as boolean in DocSearchProps.
DocSearchProps.contextualSearch is typed string, but the theme config types and validates it as a boolean. SearchBar takes Partial<DocSearchProps>, so contextualSearch={true} fails typechecking. Change the field to boolean. Also change the contextualSearch parameter of normalizeIndex to boolean, and update test fixtures that pass a string.
As per coding guidelines, not applicable.

Pass searchParameters index keys through askAi.indices.
When askAi.indices is set, DocSearch sends only those names as the Ask AI search indices. An index that appears only as a searchParameters key is sent as an override and is not searched. buildAskAiSearchParameters adds such keys to searchParameters but leaves indices unchanged, so a configured index like index-2 can produce no results. Add the union of the two key sets to the returned indices, and update the test that expects indices: ['index-1'].

Search page drops hits from every index after the first.
With several indices, the modal searches all of them, but SearchPage queries only the first one. The modal footer links to this page, so blog-only matches appear in the modal and are missing from the page. Either query all configured indices on the search page, or stop linking to it when several indices are configured.

Add the new AI and facet message IDs to the translation catalogs.
Localized sites show English text for the new AI conversation and facet controls. The IDs in SearchTranslations/index.ts have no entries in any locale catalog, so the translation lookup falls back to the English source message.

Add catalog entries for the new AI and facet translation IDs declared in
SearchTranslations, including
theme.SearchModal.searchBox.newConversationPlaceholder, so localized sites
resolve these messages instead of falling back to English.

Accept string facetFilters in searchParameters.
SearchParametersSchema only accepts an array for facetFilters. The installed DocSearch type allows a string, so a valid searchParameters: {facetFilters: 'language:en'} fails config validation. Accept a string alongside the array form.
IMPORTANT
Review the replacement and indentation, then test before committing.
Suggested change
facetFilters: FacetFiltersSchema.optional(),
facetFilters: Joi.alternatives()

Update SearchParametersSchema so facetFilters accepts either a string or the
existing FacetFiltersSchema array form, while remaining optional; preserve
validation for the existing array form.

Motivation
Upgrades
@docsearch/reactfrom v4 to v5 and removes the DocSearch v3compatibility layer that was carried during the v3/v4 transition period.
DocSearch v5 drops the old v3 APIs and introduces multi-index search and
Agent Studio-based Ask AI, neither of which can be expressed with the previous
single-index (
indexName+ top-levelsearchParameters) configuration. This PRmigrates the theme config surface accordingly.
What changed
@docsearch/reactto^5.0.4(+ lockfile)algolia.indicesarray option (acceptsstringor{name, searchParameters}entries)(
@docsearch/react/modal/@docsearch/react/askaiModal)assistantId→agentId, per-indexsearchParameters, and newmemory/promptSuggestionsoptionsfacetFiltersinto Agent Studiofiltersstrings(new
facetFiltersToFilterString/mergeFiltersutilities)declarations, and the
ensureAskAISupportedguardSearchTranslationsfor v5 labelsBreaking changes
@docusaurus/theme-search-algoliaassistantId→agentId@docsearch/reactv5 is installedmulti-index + Agent Studio Ask AI, which the old single-index config cannot express
(mostly a config rename)
Bundle size
Note
There is an open issue to track removing the
@base-ui/reactdep from DocSearch here, which would reduce the overall bundles by~51 kB.Test Plan
