 If you use the autoCommit feature on the Solr core you probably don't want to use the commit command, because that would trigger a commit in between the autoCommit interval. In all other cases it makes sense to add a commit to your update (or at least to the last update request if you issue multiple) to apply your update to the Solr index.
 
-This command command starts the commit process on the server, bit the actual commit process might take a while. If your update command with a commit returns successfully this only means Solr received the commands and is processing them, the result might not be visible for a while. The time this takes depends on many factors: hardware, index size, number of index segments, the commands to execute, the search load, etcetera. It can vary between milliseconds and minutes.
