Search Types Comparison

Semantic Search (`/knowledge/search`)

Best for:

Natural language questions
Conceptual searches
Finding related content
Discovering relevant information
Understanding context and meaning

How it works:

Converts query to vector embedding
Uses vector similarity matching
Returns results ranked by semantic relevance
Scores indicate similarity (0-1)

Example queries:

"How do I reset my password?"
"Best practices for API integration"
"Troubleshooting connection issues"

Title Search (`/knowledge/search-title`)

Best for:

Finding specific documents by name
Exact title lookups
Browsing by name
Autocomplete functionality

How it works:

Performs partial string matching on titles
Case-insensitive matching
Returns results ordered by creation date
No relevance scoring

Example queries:

"Installation Guide"
"API Reference"
"User Manual"

Use Cases

Natural Language Q&A

// User asks a question
const question = "What are the system requirements?";
const results = await searchKnowledge(question);
 
// Display relevant knowledge
results.results.forEach(item => {
  console.log(`${item.title}: ${item.content.substring(0, 200)}...`);
});

Document Finder

// Find specific documents by title
async function findDocument(titleQuery) {
  const response = await fetch(
    `${BASE_URL}/workspaces/${WORKSPACE_ID}/knowledge/search-title`,
    {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${API_KEY}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ title: titleQuery })
    }
  );
  return await response.json();
}
 
const docs = await findDocument('API Reference');

Content Discovery

// Discover related content
const related = await searchKnowledge(
  'machine learning best practices',
  { limit: 5 }
);

Role-Based Content Access

// Search within user's accessible content
const userResults = await searchKnowledge(
  'product features',
  { roleIds: currentUser.roleIds }
);

Best Practices

Write Effective Queries

// Be specific
const specific = await searchKnowledge('OAuth 2.0 authentication setup');
 
// Rather than too broad
const broad = await searchKnowledge('authentication');

Set Appropriate Limits

// For autocomplete: small limit
const suggestions = await searchKnowledge(userInput, { limit: 5 });
 
// For comprehensive results: larger limit
const comprehensive = await searchKnowledge(query, { limit: 50 });

Handle Empty Results

const results = await searchKnowledge(query);
 
if (results.total === 0) {
  console.log('No results found. Try a different query.');
} else {
  displayResults(results.results);
}

Use Score Threshold

// Filter by relevance score
const highQualityResults = results.results.filter(item => item.score >= 0.8);

Cache Frequent Searches

const searchCache = new Map();
 
async function cachedSearch(query) {
  const cacheKey = `search:${query}`;
 
  if (searchCache.has(cacheKey)) {
    return searchCache.get(cacheKey);
  }
 
  const results = await searchKnowledge(query);
  searchCache.set(cacheKey, results);
 
  // Expire cache after 5 minutes
  setTimeout(() => searchCache.delete(cacheKey), 5 * 60 * 1000);
 
  return results;
}

Search Algorithm

Semantic Search Process

Query Processing: Query is converted to a vector embedding using the same model as knowledge content
Vector Search: Performs cosine similarity search against all knowledge embeddings
Relevance Ranking: Results are ranked by similarity score (0-1 scale)
Filtering: Applies audience and role filters if specified
Limiting: Returns top N results based on limit parameter

Title Search Process

Pattern Matching: Performs case-insensitive partial match on title field
Database Query: Uses SQL LIKE or similar for matching
Filtering: Applies audience and role filters if specified
Ordering: Results ordered by creation date (newest first)
Limiting: Returns top N results based on limit parameter

Notes

Search Indexing

New knowledge items are searchable within seconds of creation
Semantic search uses vector embeddings for similarity matching
Search results reflect current RBAC permissions
Deleted items are removed from search indexes immediately

Result Ordering

Semantic search: Results ordered by relevance score (highest first)
Title search: Results ordered by creation date (newest first)

Content Excerpts

Response includes content excerpts (first 500 characters) for preview. Use the Get Knowledge endpoint to retrieve full content.

Audience and Role Filtering

When audienceId is provided, only knowledge assigned to that audience is returned
When roleIds is provided, only knowledge accessible to those roles is returned
Both filters can be combined for fine-grained access control

Performance Considerations

Semantic search is more computationally intensive than title search
Keep query strings concise for best performance
Use pagination (limit) to manage large result sets
Consider caching for frequently searched queries
