        theTime - timeout duration, must be a positive number
        theTimeUnit - the unit of time for the timeout, cannot be null

        Optimizes the indexes of a given database for query answering and disk utilization after the database has been heavily modified.

        Parameters:
        theName - the name of the database to optimize
        theOptions - options specifying the specific optimization steps to perform or empty for default optimizations
