8.3. Adjusting optimization

Apache Lucene has a few parameters to influence how optimization is performed. Hibernate Search exposes those parameters.
Further index optimisation parameters include:
  • hibernate.search.[default|<indexname>].indexwriter.[batch|transaction].max_buffered_docs
  • hibernate.search.[default|<indexname>].indexwriter.[batch|transaction].max_field_length
  • hibernate.search.[default|<indexname>].indexwriter.[batch|transaction].max_merge_docs
  • hibernate.search.[default|<indexname>].indexwriter.[batch|transaction].merge_factor
  • hibernate.search.[default|<indexname>].indexwriter.[batch|transaction].ram_buffer_size
  • hibernate.search.[default|<indexname>].indexwriter.[batch|transaction].term_index_interval
See Section 4.8, “Tuning Lucene indexing performance” for more details.
