+# 🦹 Combine pre-filtering with vector search
+
+Pre-filtering a technique to optimize vector search by only considering documents that match certain criteria during vector search.
+
+Fill in any `<CODE_BLOCK_N>` placeholders and run the cells under the **🦹‍♀️ Combine pre-filtering with vector search** section in the notebook to get a sense of how to combine pre-filtering with MongoDB Atlas Vector Search.
+
+:::caution
+**DO NOT** actually modify the existing vector index definitions in the Atlas UI, or the existing pipeline definitions in the code.

+
+The answers for code blocks in this section are as follows:
