Problem Statement:

Provide a design overview of a basic search engine. Your search engine system must support the following:

- **Retrieval:** The search engine should display a list of relevant web pages in response to a user query. The results should include the page title, URL, and a brief summary.

- **Indexing:** The system should be able to crawl and index web pages from the Internet. The indexing process should store metadata about the web pages, such as their URL, title, and a brief summary.

- **Scalability:** The system should be designed to handle a large number of queries and indexed web pages, ensuring that response times remain low as the search engine scales.

Finer concerns such as query processing & page ranking can be briefly addressed, but are not mandatory.
