init

codebolt.search.init(engine: string): void

Initializes the search module with the specified search engine.

Parameters​

  • engine (string): The search engine to use (default: "bing"). Supported engines include "bing", "google", etc.

Returns​

  • void: No return value.

Example 1: Initialize with Default Engine​

// Initialize with default Bing search engine
await codebolt.search.init();
console.log('Search module initialized with Bing');

Example 2: Initialize with Google​

// Initialize with Google search engine
await codebolt.search.init('google');
console.log('Search module initialized with Google');

// Now perform searches using Google
const results = await codebolt.search.search('JavaScript async await');
console.log('Google search results:', results);

Example 3: Initialize and Search Pattern​

// Common pattern: initialize before searching
async function performSearch(query, engine = 'bing') {
  // Initialize with preferred engine
  await codebolt.search.init(engine);

  // Perform the search
  const results = await codebolt.search.search(query);

  return results;
}

// Usage
const data = await performSearch('React hooks tutorial', 'google');
console.log('Search completed:', data);

Example 4: Multiple Search Sessions​

// Search with different engines for comparison
async function compareEngines(query) {
  // Search with Bing
  await codebolt.search.init('bing');
  const bingResults = await codebolt.search.search(query);

  // Search with Google
  await codebolt.search.init('google');
  const googleResults = await codebolt.search.search(query);

  return {
    bing: bingResults,
    google: googleResults
  };
}

const comparison = await compareEngines('TypeScript vs JavaScript');
console.log('Engine comparison:', comparison);

Example 5: Conditional Initialization​

// Initialize based on environment or configuration
async function setupSearch(config) {
  const engine = config.preferredEngine || 'bing';

  try {
    await codebolt.search.init(engine);
    console.log(`Initialized with ${engine}`);
    return true;
  } catch (error) {
    console.error('Failed to initialize search:', error);
    return false;
  }
}

// Usage
const success = await setupSearch({ preferredEngine: 'google' });
if (success) {
  const results = await codebolt.search.search('web development');
  console.log(results);
}

Example 6: Re-initialization Pattern​

// Re-initialize to switch search engines
async function switchEngine(newEngine) {
  console.log(`Switching to ${newEngine}...`);

  // Re-initialize with new engine
  await codebolt.search.init(newEngine);

  // Verify by performing a test search
  const testResult = await codebolt.search.search('test');

  return testResult;
}

// Start with Bing
await codebolt.search.init('bing');

// Later switch to Google
await switchEngine('google');

Explanation​

The codebolt.search.init(engine) function initializes the search module with a specified search engine. This is typically the first function you call before performing any search operations.

Key Points:

  • Default Engine: If no engine is specified, defaults to "bing"
  • Supported Engines: Common engines include "bing", "google" (availability depends on configuration)
  • Re-initialization: You can call init() again to switch search engines
  • No Return Value: The function returns void, so you cannot verify initialization success from the return value

Common Use Cases:

  • Setting up the search module before use
  • Switching between different search engines
  • Configuring search behavior based on user preferences or requirements

Best Practices:

  1. Always initialize before performing searches
  2. Consider error handling if initialization fails
  3. Choose the appropriate engine for your use case
  4. Re-initialize only when you need to change engines

Notes:

  • The exact list of supported search engines may vary based on configuration
  • Some search engines may require additional API keys or configuration
  • Initialization failures may not throw errors; validate with a test search
