(PECL solr >= 0.9.2)
SolrClient::optimize — Defragments the index
$maxSegments= 1 [, bool
$softCommit= true [, bool
$waitSearcher= true ]]] )
Defragments the index for faster search performance.
Optimizes down to at most this number of segments. Since Solr 1.3
This will refresh the 'view' of the index in a more performant manner, but without "on-disk" guarantees. (Solr4.0+)
Block until a new searcher is opened and registered as the main query searcher, making the changes visible.
Returns a SolrUpdateResponse on success or throws an exception on failure.
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.
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".
