- Introduced a detailed guide on query filters in the README, covering basic filtering, comparison operators, array operators, logical operators, element operators, and advanced filtering patterns.
- Implemented a type-safe filtering system in `classes.doc.ts` with `MongoFilterCondition` and `MongoFilter` types to support MongoDB operators while maintaining nested type safety.
- Enhanced error handling for invalid operators and conditions in the filtering logic.
- Added extensive tests for various filtering scenarios, including basic, comparison, array, logical, and complex filters, ensuring robust functionality and performance.
- Implemented security measures to prevent the use of dangerous operators like `$where` and validate operator usage.
