📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal:

The session aimed to enhance the integration of document indexing in Haystack with web crawling outputs, focusing on improving data structure alignment and error handling.

Key Activities:

• Reviewed the workflow for indexing documents in Haystack, emphasizing the use of index_structured_docs and adapt_scraped_docs functions.
• Compared different indexing methods in Haystack, evaluating their strengths and limitations.
• Aligned JSON file structures with the expected format for index_files in Haystack, including organizing files by path, meta, and content.
• Modified a Python script to save web-scraped pages as Markdown files, organized by subdomain.
• Developed a function index_saved_md_files() to connect Markdown outputs to the Haystack indexing pipeline.
• Provided step-by-step guidance for running a Streamlit app and resolved a Path.glob() error in Python.
• Diagnosed issues with the fetch(...) function in a Git repository and implemented a web crawling function using the Spider API.
• Proposed a web exploration strategy to enhance Matías Iglesias’ positioning in the scientific and academic ecosystem of Buenos Aires.

Achievements:

• Successfully integrated web crawling outputs with Haystack indexing.
• Improved error handling and debugging processes for Python scripts related to web scraping and indexing.

Pending Tasks:

• Further testing and validation of the new indexing functions and web crawling integrations.
• Exploration of additional web sources for strategic positioning.
