Before using value, delete SBC spaces before and after it. The value cannot contain the following special characters: +/?#&=,% If the tag value is left blank, it indicates any_value (querying any value). To query instances with multiple tag key-value pairs, separate the pairs with commas (,). A maximum of 10 key-value pairs are supported.
