 ** condition **   <a name="DiscServ-Type-Filter-condition"></a>
A conditional operator. The following operators are valid: EQUALS, NOT\$1EQUALS, CONTAINS, NOT\$1CONTAINS. If you specify multiple filters, the system utilizes all filters as though concatenated by *AND*. If you specify multiple values for a particular filter, the system differentiates the values using *OR*. Calling either *DescribeConfigurations* or *ListConfigurations* returns attributes of matching configuration items.
