## What is Bit Rot protection?

- Use batch operations for indexing (100-500 items)
- Don't call `refresh()` too frequently
- Limit `maxReadingNum` to prevent memory issues
- OpenSearch auto-refreshes every 1 second by default

### Compatibility
- Designed for OpenSearch 2.x+
- All text processing uses UTF-8

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

With it, you can use <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> directly with **FastAPI**.

        return parse(stream, Constants.UTF_8);
    }

    /**
     * Parses a robots.txt file from the given input stream using the specified character encoding.
     *
     * <p>This method is designed to be resilient to malformed robots.txt files.
     * It will parse valid directives and ignore invalid ones, ensuring that partial
     * content can be extracted even from poorly formatted files.</p>

/**
 * Utility class for document data manipulation and type conversion.
 * This class provides static methods for extracting typed values from document maps,
 * URL encoding, and other document-related operations. It's designed as a final
 * utility class with only static methods.

Now let's go back a bit and understand what is all that.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.

OAuth2 was designed so that the backend or API could be independent of the server that authenticates the user.

But in this case, the same **FastAPI** application will handle the API and the authentication.
