If the client requests that the data be filtered (typically by matching a "starts-with" test of the value), then this property holds the string to be tested against. If this option is left unchanged, the system filters the results. The developer has the option to apply the filter here, after which the filter property should be changed to be an empty string or a Boolean false, so that the system does not try to apply the filter again. This option is available to apply more-efficient filtering techniques (such as a SQL "WHERE" clause, in the case of selecting from a database). This option applies only to Multiselect Elements, not Enumeration Elements.
