+# RAG Wikipedia
+This package provides an end-to-end example of performing vector search and Retrieval-Augmented Generation (RAG) from an OCI Data Science Notebook Session using Wikipedia's Artificial Intelligence page.
+
+Reviewed: 2025.11.27
+
+# When to use this asset?
+
+Use this asset as support material when wanting to showcase Oracle AI Vector Search within Oracle AI Database 26ai. The asset includes explanations along with advanced RAG techniques, including:
+
+1. Comparing rule-based and semantic-based text splitters
+2. Connecting to the Oracle AI Database 26ai and creating vector-enabled tables
+3. Running hybrid search (keyword + vector similarity)
+4. Applying rerankers to improve retrieved context
+
+# Prerequisites
+
+To use this package, you need:
+- Basic Python knowledge
+- Access to an OCI Data Science Notebook Session
+- An Oracle AI Database 26ai or 23ai with Vector Search enabled
+- Required IAM permissions for Data Science and Database access
+- A configured database wallet or secure connection details
+
+# Environment
+
+Run the examples in a Jupyter Notebook inside an OCI Data Science Notebook Session.
