Optimize
editOptimize
editThe optimize API allows to optimize one or more indices through an API. The optimize process basically optimizes the index for faster search operations (and relates to the number of segments a Lucene index holds within each shard). The optimize operation allows to reduce the number of segments by merging them.
$ curl -XPOST 'http://localhost:9200/twitter/_optimize'
Request Parameters
editThe optimize API accepts the following request parameters:
|
The number of segments to optimize to. To fully
optimize the index, set it to |
|
Should the optimize process only expunge segments with
deletes in it. In Lucene, a document is not deleted from a segment, just marked
as deleted. During a merge process of segments, a new segment is created that
does not have those deletes. This flag allows to only merge segments that have
deletes. Defaults to |
|
Should a flush be performed after the optimize. Defaults to
|
|
Should the request wait for the merge to end. Defaults
to |
|
[1.4.0] Deprecated in 1.4.0. Use the upgrade API |
Multi Index
editThe optimize API can be applied to more than one index with a single
call, or even on _all
the indices.
