Whoosh is also now smarter about using mmap.</li> <li>Added functionality to index and search hierarchical documents. See <a class="reference internal" href="../nested.html"><em>Indexing and searching document hierarchies</em></a>.</li> <li>Rewrote the Directed Acyclic Word Graph implementation (used in spell checking) to be faster and more space-efficient.
