Parameters:

maxSegments

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.

Returns:

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

Exception:

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.
