​

Key Features & Functions

​

Input Parameters for Each Function

​

1. _search_google

Parameters

​

2. _scrape_url

Parameters

​

Use Cases

1. Dynamic Web Searches

   • Automatically query Google for information related to tasks or datasets.

   • Example: Querying “Snowflake best practices” when preparing training modules.

2. Targeted Web Scraping

   • Fetch and parse specific page elements by CSS selectors.

   • Example: Extracting stock updates from a financial news site to compile daily performance summaries.

3. Data Enrichment

   • Incorporate scraped content into existing data pipelines or reports.

   • Example: Appending scraped customer reviews to a dataset for sentiment analysis.

4. Checking for Updates

   • Periodically scrape pages to monitor changes.

   • Example: Tracking a documentation page for new best practices or feature releases.

​

Workflow/How It Works

1. Step 1: Input the Search Query

   • For _search_google, provide a keyword/phrase in query to retrieve structured search results.

2. Step 2: Review Results

   • Use the returned URLs, titles, and snippets for further action in your workflow.

3. Step 3: Scrape Webpage Content

   • Call _scrape_url, passing the desired site URL and any element_selector to extract relevant parts.

4. Step 4: Parse & Utilize

   • Integrate scraped or searched data into your pipelines or processes, such as building reports or enriching datasets.

​

Integration Relevance

• Metadata Discovery: Combine with data_connector_tools to enrich databases or workflows with context from web pages.

• Workflow Scheduling: Pair with process_scheduler_tools to run periodic scrapes or searches.

• Testing Validation: Collaborate with manage_tests_tools to validate that web-scraped data meets expected outcomes.

​

Configuration Details

• For _search_google, carefully craft queries to return targeted results while avoiding rate-limit breaches or irrelevant hits.

• For _scrape_url, specify precise CSS selectors (element_selector) if you only need specific components.

​

Limitations or Notes

1. Google API Restrictions

   • Rapid or large-volume queries may encounter rate limits. Query responsibly and consider caching or batching results.

2. Dynamic & JavaScript Pages

   • HTML-based scraping may fail on sites requiring JavaScript rendering. Use alternate methods or services for dynamic content.

3. Data Integrity

   • Scraped content can be unstructured; post-processing might be necessary before integrating the data into workflows.

4. Compliance

   • Always follow site-specific scraping rules and adhere to relevant regulations or privacy policies.

​

Output

• Search Results

  • JSON-formatted results for _search_google, including URL, title, and snippet fields.

• Scraped Content

  • Raw HTML or subsets of page content identified by element_selector from _scrape_url.

• Error Handling

  • Warnings or exceptions if the site or URL is unavailable or if query or scraping parameters are invalid.

​

How It Works

Users specify a target URL or search query, and the tool returns the relevant content—either through direct scraping (_scrape_url) or via broader Google search (_search_google). This content can be parsed, stored, or directly integrated into downstream workflows for analysis or reporting.
