+End-to-end example demonstrating usage frequency tracking in Cognee.
+
+This example shows how to:
+1. Add data and build a knowledge graph
+2. Run searches with save_interaction=True to track usage
+3. Extract and apply frequency weights using the memify pipeline
+4. Query and analyze the frequency data
+
+The frequency weights can be used to:
+- Rank frequently referenced entities higher during retrieval
+- Adjust scoring for completion strategies
+- Expose usage metrics in dashboards or audits
