Is it supported to limit the range of query results based on radius? and how？

I read the documentation and source code, but I didn't find a way to set the radius to limit the number of returned results. Only found a way to set the number of returned results through the topk parameter.

Currently, we only support returning topK results. Can you describe your scenario where a radius needs to be set? For example, if you set it to [10, 30], what should be returned?

If you are talking about range search, this is in our plan for future implementations.

I use milvus to retrieve similar texts. I use cosine similarity as the scoring criterion. So I want to set a value of cosine similarity to limit the number of returns, such as setting to only return vectors with cosine similarity greater than 0.5.

I understand your point, this is range search which we haven't supported yet.
