Variable filtering expressions are comma-separated and are structured as follows: A valid parameter value has the form `key_operator_value`. `key` is the variable name, `operator` is the comparison operator to be used and `value` the variable value.Note: Values are always treated as `String` objects on server side. Valid operator values are: `eq` - equal to; `neq` - not equal to; `gt` - greater than; `gteq` - greater than or equal to; `lt` - lower than; `lteq` - lower than or equal to; `like`. `key` and `value` may not contain underscore or comma characters.
