    • Method Detail

      • setMinMergeDocs

        public void setMinMergeDocs​(int minMergeDocs)
        Sets the minimum size for the lowest level segments. Any segments below this size are candidates for full-flush merges and merged more aggressively in order to avoid having a long tail of small segments. Large values of this parameter increase the merging cost during indexing if you flush small segments.
      • getMinMergeDocs

        public int getMinMergeDocs()
        Get the minimum size for a segment to remain un-merged.
