+
+Key difference between v1 and v2 get memories:
+
+• **Filters**: v2 allows you to apply filters to narrow down memory retrieval based on specific criteria. This includes support for complex logical operations (AND, OR) and comparison operators (IN, gte, lte, gt, lt, ne, icontains) for advanced filtering capabilities.
+
+The v2 get memories API is more powerful and flexible, allowing for more precise memory retrieval without the need for a search query.
