# SolrClient::commit

(PECL solr >= 0.9.2)

SolrClient::commit — Finalizes all add/deletes made to the index

### Description

public SolrUpdateResponse SolrClient::commit ([ bool `$softCommit` = false [, bool `$waitSearcher` = true [, bool `$expungeDeletes` = false ]]] )

This method finalizes all add/deletes made to the index.

### Parameters

`softCommit`

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

  A soft commit is much faster since it only makes index changes visible and does not fsync index files or write a new index descriptor. If the JVM crashes or there is a loss of power, changes that occurred after the last hard commit will be lost. Search collections that have near-real-time requirements (that want index changes to be quickly visible to searches) will want to soft commit often but hard commit less frequently.

`waitSearcher`

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

`expungeDeletes`

  Merge segments with deletes away. (Solr1.4+)

### Return Values

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

### Errors/Exceptions

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.
