  • Method Details

    • getNprobe

      int getNprobe()
       How many buckets to query, the default is 80, and cannot exceed the size of ncentroids Optional parameters
      int32 nprobe = 1;
      Returns:
      The nprobe.

    • getParallelOnQueries

      int getParallelOnQueries()
       Default 1, parallel between queries; 0, parallel in a single query.
 Inter-query parallelism refers to a query in which a single query contains multiple vectors, and is parallelized
 between each vector query. If there is only a single vector, it can be queried in parallel across nprobe buckets
 optional parameters
      int32 parallel_on_queries = 2;
      Returns:
      The parallelOnQueries.

    • getRecallNum

      int getRecallNum()
       number of results recalled from the index
 The default is 100. This parameter is for whether to use the original vector for fine sorting. When searching, it
 will look for recall_num results in the IVF index. Then use the original vectors to reorder to get the topK final
 results. Among them, whether to use the original vector to reorder is specified by the quick parameter. optional
 parameters
      int32 recall_num = 3;
      Returns:
      The recallNum.
