New features

  • Updated hnswlib to nmslib/hnswlib@c5c38f0 (20 September 2019).
  • A new method, markDeleted, that will remove an object from being retrieved from the index.
  • A new method, resizeIndex, that allows the index to be increased without having to save and reload the index.
  • A new method, size is available for the index objects and reports the number of items added to the index.

Bug fixes and minor improvements

  • hnsw_search would stop if the number of rows in the input matrix was smaller than k. This check has been removed. Note that the correct behavior is to ensure that k is smaller than or equal to index$size() where index is the index you are searching. Because the size() method is new to this version, to preserve compatibility with old indexes, this check hasn't been added to hnsw_search. If this matters to you, manually compare index$size() with k before running hnsw_search. An error will be thrown if k neighbors can't be found in the index. Thank you to Yuxing Liao for spotting this and the pull request to remove the check.
