feat(theme-search-algolia): add support for DocSearch v4.3.2 and new Suggested Questions

[NatanTechofNY]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

This PR adds support for the new suggestedQuestions parameter introduced in DocSearch v4.3, which allows users to enable or disable suggested questions in the Ask AI interface. Additionally, it updates the DocSearch dependency from ^4.1.0 to ^4.3.2 to support this new feature while maintaining backward compatibility with DocSearch v3.9+.

The suggestedQuestions option provides users with pre-configured questions they can click to quickly get started with Ask AI, improving the user experience when using the Ask AI feature.

Test Plan

Code Changes

1. Type Definitions (packages/docusaurus-theme-search-algolia/src/theme-search-algolia.d.ts):

   • Added suggestedQuestions?: boolean to the AskAiConfig type
   • Maintained backward compatibility with DocSearch v3.9+

2. Validation Schema (packages/docusaurus-theme-search-algolia/src/validateThemeConfig.ts):

   • Added suggestedQuestions: Joi.boolean().optional() validation
   • Ensures type safety at runtime

3. Unit Tests (packages/docusaurus-theme-search-algolia/src/__tests__/validateThemeConfig.test.ts):

   • ✅ Added test for suggestedQuestions: true
   • ✅ Added test for suggestedQuestions: false
   • ✅ Added test to reject invalid string type
   • ✅ Added test to reject invalid number type

4. Component Updates:

   • Updated SearchBar/index.tsx and useAlgoliaAskAi.ts with proper type handling
   • Added type assertions to ensure compatibility across DocSearch versions

5. Documentation (website/docs/search.mdx and website/versioned_docs/version-3.9.2/search.mdx):

   • Updated Ask AI configuration examples to show suggestedQuestions parameter
   • Added inline comments explaining the feature

6. Dependency Update (packages/docusaurus-theme-search-algolia/package.json):

   • Updated from "@docsearch/react": "^3.9.0 || ^4.1.0"
   • Updated to "@docsearch/react": "^3.9.0 || ^4.3.2"

Manual Testing

To test the new feature:

export default {
  themeConfig: {
    algolia: {
      appId: 'YOUR_APP_ID',
      apiKey: 'YOUR_API_KEY',
      indexName: 'YOUR_INDEX_NAME',
      askAi: {
        assistantId: 'YOUR_ASSISTANT_ID',
        suggestedQuestions: true, // Enable suggested questions
      },
    },
  },
};

Backward Compatibility

✅ Fully backward compatible with:

• DocSearch v3.9 (without Ask AI)
• DocSearch v4.0-4.2 (with Ask AI, without suggested questions)
• DocSearch v4.3+ (with Ask AI and suggested questions)

Screenshots

v4.3.2 includes the following new features:

• Stop a streaming answer
• Fix for copy button
• New kebab menu on Ask AI screen which includes 2 new options: Conversation History and Start New Conversation.
• New screen for "Conversation History" from the Ask AI view
• New screen for "Start New Conversation" from Ask AI view
• This screen will show any suggested questions users might want to ask.
