|Optimizes the meta data and indexes of the database {{Code|$db}}.<br/>If {{Code|$all}} is {{Code|true}}, the complete database will be rebuilt.<br/>The {{Code|$options}} argument can be used to control indexing. The syntax is identical to the [[#db:create|db:create]] function: Allowed options are all [[Options#Indexing|indexing]] and [[Options#Full-Text|full-text]] options. <code>[[Options#UPDINDEX|UPDINDEX]] </code> is only allowed supported if {{Code|$all}} is {{Code|true}}.
