 PageIndex currently enables reasoning-based RAG within a single document by default.
 For users who need to search across multiple documents, we provide three best-practice workflows for different scenarios below.
 
-* [**Search by Metadata**:](dmetadata.md) for documents that can be distinguished by metadata.
+* [**Search by Metadata**:](metadata.md) for documents that can be distinguished by metadata.
 * [**Search by Semantics**:](semantics.md) for documents with different semantic content or cover diverse topics.
 * [**Search by Description**:](description.md) a lightweight strategy for a small number of documents.
