 # With Iterators
 
-Milvus provides search and query iterators for iterating results with a large volume of entities. Since Milvus limits TopK to 16384, users can use iterators to return large numbers or even whole entities in a collection in batch mode.

 ## Overview
 
-Iterators are powerful tools that help you iterate through a large volume of or all data within a collection using primary key values and Boolean expressions. This can significantly improve the way you retrieve data. Unlike the traditional use of __offset__ and __limit__ parameters, which may become less efficient over time, iterators offer a more scalable solution.
+Iterators are efficient tool for scanning a whole collection or iterating through a large volume of entities by specifying primary key values or a filter expression. Compared to a search or query call with __offset__ and __limit__ parameters, using iterators is more efficient and scalable.
