SolrClient::optimize

Defragments the index

&reftitle.description; public `SolrUpdateResponse` `SolrClient::optimize` `int` `maxSegments` 1 `bool` `softCommit`&true; `bool` `waitSearcher`&true;

Defragments the index for faster search performance.

&reftitle.parameters;

`maxSegments`

- Optimizes down to at most this number of segments. Since Solr 1.3

`softCommit`

- This will refresh the 'view' of the index in a more performant manner, but without "on-disk" guarantees. (Solr4.0+)

`waitSearcher`

- Block until a new searcher is opened and registered as the main query searcher, making the changes visible.

&reftitle.returnvalues;

Returns a SolrUpdateResponse on success or throws an exception on failure.

&reftitle.errors;

Throws `SolrClientException` if the client had failed, or there was a connection issue.

Throws `SolrServerException` if the Solr Server had failed to process the request.

&reftitle.notes;

PECL Solr >= 2.0 only supports Solr Server >= 4.0

Prior to PECL Solr 2.0 this method used to accept these arguments "int $maxSegments, bool $waitFlush, bool $waitSearcher".
