    • Added NEXT_PUBLIC_MEILISEARCH_URL
    • Added MEILISEARCH_MASTER_KEY
    • Added NEXT_PUBLIC_MEILISEARCH_PUBLIC_KEY (search-only key for direct browser access)

cd /Users/admin/Sites/nself-chat
pnpm install

This will install the meilisearch npm package (v0.44.0).

Copy the example environment file and add MeiliSearch configuration:

cp .env.example .env.local

Add to .env.local:

NEXT_PUBLIC_MEILISEARCH_URL=http://search.localhost:7700
MEILISEARCH_MASTER_KEY=nchat-search-dev-key-32-chars-long

# Optional: public (search-only) API key for direct browser access.
# When set, the frontend queries MeiliSearch directly without a proxy round-trip.
# Leave unset to use the /api/plugins/search/search proxy (safe default).
# NEXT_PUBLIC_MEILISEARCH_PUBLIC_KEY=<search-only-api-key>

Check if MeiliSearch is enabled in .backend/.env.dev:

cd .backend
cat .env.dev | grep MEILISEARCH

Should show:

SEARCH_ENGINE=meilisearch
MEILISEARCH_ENABLED=true
MEILISEARCH_VERSION=v1.5
MEILISEARCH_MASTER_KEY=nchat-search-dev-key-32-chars-long
MEILISEARCH_PORT=7700

Start the backend if not running:

cd .backend
nself start

Verify MeiliSearch is running:

nself status | grep meilisearch

Or check directly:

curl http://search.localhost:7700/health

Apply the search features migration:

cd .backend
nself db migrate

This creates:

• nchat_search_history table
• nchat_saved_searches table
• Message flag columns (has_link, has_file, has_image, is_pinned, is_starred)
• Full-text search indexes

Run the initialization endpoint to create and configure indexes:

curl -X POST http://localhost:3000/api/search/initialize

Or use the health check to verify:

curl http://localhost:3000/api/search/initialize

pnpm dev

Press Cmd+K (Mac) or Ctrl+K (Windows/Linux) to open the search modal.

Type your search query:

project update

Use operators to filter results:

project update from:john in:general has:file after:2024-01-01

Click the "Filters" button to access:

• Date range picker
• Channel/user filters
• Content type toggles
• Sort options

1. Enter your search query
2. Press Cmd+S or Ctrl+S
3. Enter a name for the search
4. Click OK

1. Click "Saved" button in search modal
2. Click on a saved search to load it

Content should be automatically indexed when:

• A message is created
• A file is uploaded
• A user is registered
• A channel is created

To implement automatic indexing, add indexing calls to your create/update handlers:

import { indexMessage } from '@/lib/search/indexer'

// After creating a message
await indexMessage({
  id: message.id,
  content: message.content,
  author_id: message.author_id,
  author_name: message.author_name,
  channel_id: message.channel_id,
  channel_name: message.channel_name,
  created_at: message.created_at,
  has_link: /https?:\/\//.test(message.content),
  has_file: message.attachments?.length > 0,
  has_image: message.attachments?.some((a) => a.mime_type.startsWith('image/')),
  is_pinned: false,
  is_starred: false,
})

To index existing content, create a script:

// scripts/reindex-search.ts
import {
  reindexAllMessages,
  reindexAllFiles,
  reindexAllUsers,
  reindexAllChannels,
} from '@/lib/search/indexer'
import { apolloClient } from '@/lib/apollo-client'
import { GET_ALL_MESSAGES, GET_ALL_FILES, GET_ALL_USERS, GET_ALL_CHANNELS } from '@/graphql/queries'

async function reindex() {
  console.log('Reindexing all content...')

  // Messages
  const fetchMessages = async () => {
    const { data } = await apolloClient.query({ query: GET_ALL_MESSAGES })
    return data.messages.map((m) => ({
      id: m.id,
      content: m.content,
      author_id: m.author_id,
      author_name: m.author.display_name,
      channel_id: m.channel_id,
      channel_name: m.channel.name,
      created_at: m.created_at,
      has_link: /https?:\/\//.test(m.content),
      has_file: m.attachments?.length > 0,
      has_image: m.attachments?.some((a) => a.mime_type.startsWith('image/')),
      is_pinned: m.is_pinned || false,
      is_starred: m.is_starred || false,
    }))
  }

  await reindexAllMessages(fetchMessages)

  // Files
  await reindexAllFiles(fetchFiles)

  // Users
  await reindexAllUsers(fetchUsers)

  // Channels
  await reindexAllChannels(fetchChannels)

  console.log('Reindexing complete!')
}

reindex().catch(console.error)

Run the script:

pnpm tsx scripts/reindex-search.ts

# Health check
curl http://search.localhost:7700/health

# Check version
curl http://search.localhost:7700/version

# Initialize indexes
curl -X POST http://localhost:3000/api/search/initialize

# Check index stats
curl http://search.localhost:7700/indexes/messages/stats

# Simple search
curl -X POST http://localhost:3000/api/search \
  -H "Content-Type: application/json" \
  -d '{"query": "test"}'

# Search with operators
curl -X POST http://localhost:3000/api/search \
  -H "Content-Type: application/json" \
  -d '{"query": "test from:john in:general has:file"}'

# Quick search (GET)
curl "http://localhost:3000/api/search?q=test&limit=10"

1. Open the app: http://localhost:3000
2. Press Cmd+K to open search modal
3. Try different search queries:
   • project update
   • from:john
   • in:general
   • has:link
   • before:2024-01-01
4. Test filters:
   • Click "Filters" button
   • Select date range
   • Toggle content types
5. Test saved searches:
   • Enter a query
   • Press Cmd+S to save
   • Click "Saved" to view
   • Click a saved search to load

• Cmd+K / Ctrl+K: Open search
• Cmd+S / Ctrl+S: Save search (when search is open)
• Cmd+F / Ctrl+F: Toggle filters (when search is open)
• Escape: Close search

Add the search modal to your main layout:

// src/app/layout.tsx
import { useSearchKeyboard } from '@/hooks/use-search-keyboard'
import { SearchModal } from '@/components/search/SearchModal'

export default function RootLayout({ children }) {
  const { isSearchOpen, setIsSearchOpen } = useSearchKeyboard()

  return (
    <html>
      <body>
        {children}
        <SearchModal open={isSearchOpen} onOpenChange={setIsSearchOpen} />
      </body>
    </html>
  )
}

// src/components/layout/Header.tsx
import { Search } from 'lucide-react'
import { Button } from '@/components/ui/button'

export function Header() {
  const { openSearch } = useSearchKeyboard()

  return (
    <header>
      <Button onClick={openSearch} variant="ghost">
        <Search className="h-4 w-4 mr-2" />
        Search
        <kbd className="ml-2 px-1.5 py-0.5 bg-secondary rounded text-xs">
          ⌘K
        </kbd>
      </Button>
    </header>
  )
}

Add indexing to message creation:

// When a message is created
import { indexMessage } from '@/lib/search/indexer'

async function createMessage(content: string, channelId: string, userId: string) {
  // Create message in database
  const message = await db.messages.create({ content, channelId, userId })

  // Index for search
  await indexMessage({
    id: message.id,
    content: message.content,
    author_id: message.author_id,
    author_name: message.author.display_name,
    channel_id: message.channel_id,
    channel_name: message.channel.name,
    created_at: message.created_at,
    has_link: /https?:\/\//.test(message.content),
    has_file: false,
    has_image: false,
    is_pinned: false,
    is_starred: false,
  })

  return message
}

• Single document: ~10ms
• Bulk documents (1000): ~500ms
• Full reindex (100k): ~30s

• Simple query: ~5ms
• Complex query: ~15ms
• All types: ~20ms

1. Use bulk indexing for multiple documents
2. Index asynchronously in background jobs
3. Debounce search input (300ms recommended)
4. Paginate results (20-50 per page)
5. Schedule full reindex during off-peak hours

cd .backend
nself status
nself start

curl -X POST http://localhost:3000/api/search/initialize

1. Check if MeiliSearch is running
2. Verify indexes exist:

   curl http://search.localhost:7700/indexes

3. Check document count:

   curl http://search.localhost:7700/indexes/messages/stats

4. Reindex content if needed

Check what's using port 7700:

lsof -i :7700

Kill the process or change MeiliSearch port in .backend/.env.dev.
