## Features

- Indexing documents: The search engine maintains an index of documents, where each document is associated with a unique identifier.
- Searching: Given a query, the search engine returns the most relevant documents.
- BTree: The index is saved as a BTreeMap on the hard disk and loaded from the hard disk into RAM when the system is started.
