Question regarding DiskANN Implementation

[cdoron]

Hi @cydrain,

I am looking at the code for DiskANN https://github.com/zilliztech/knowhere/tree/main/thirdparty .
It appears to me that the code is based on an old version of DiskANN (maybe version 0.2 - https://github.com/microsoft/DiskANN/tree/0.2/src ).

Following my question on Discord, @PwzXxm wrote that "we have done some works like filtering and iterators" on top of DiskANN.

Question: What is the filtering that you have implemented? Are you referring to the label-based filtering from the https://harsha-simhadri.org/pubs/Filtered-DiskANN23.pdf paper, or is it something different altogether?

Thanks! Doron

Hi @cdoron, about filtering, same purpose but different implementation, since we did it one year before this paper. Also some small patches that to solve some users' corner cases.

We are more than welcome for any effort try to update our DiskANN implementation
