  • partition_num : how many partition to slot, default is 1
  • replica_num: how many replica has , recommend 3
  • engine
  • max_size : max documents for each partition
  • index_size : default 100000, if index_size == 0 it will not auto indexed, if insert document num >= index_size , it will auto indexed
  • nprobe : scan clustered buckets, default 10, it should be less than ncentroids
  • metric_type : inner product or L2
  • ncentroids : coarse cluster center number, default 256
  • nsubvector : the number of sub vector, default 32, only the value which is multiple of 4 is supported now
  • nbits_per_idx : bit number of sub cluster center, default 8, and 8 is the only value now
  • keyword
  • array : whether the tags for each document is multi-valued, true or false default is false
  • index : supporting numeric field filter default false
