Three new properties that can be used to reduced the amount of time needed to reindex the search index has been added to portal(-ext).properties.

#

1. Set how often index updates will be committed. Set the batch size to
2. configure how many consecutive updates will trigger a commit. If the value
3. is 0, then the index will be committed on every update. Set the time
4. interval in milliseconds to configure how often to commit the index. The
5. time interval is not read unless the batch size is greater than 0 because
6. the time interval works in conjunction with the batch size to guarantee
7. that the index is committed after a specified time interval. Set the time
8. interval to 0 to disable committing the index by a time interval.

   lucene.commit.batch.size=0
   lucene.commit.time.interval=0

#

1. Set Lucene's buffer size in megabytes. Higher numbers mean indexing goes
2. faster but uses more memory.

   lucene.buffer.size=16
