* @param string $name name of the index to be created

|
* @param array $definition associative array that defines properties of the index to be created.
|
|
* Currently, only one property named FIELDS is supported. This property

|
|
* indexes. Each entry of this array is set to another type of associative
|
|
* array that specifies properties of the index that are specific to

* each field.
|
|
*
|
|
* Currently, only the sorting property is supported. It should be used

|
|
* ascending or descending.
|
|
*
|
|
* Not all DBMS support index sorting direction configuration. The DBMS
|
|
* drivers of those that do not support it ignore this property. Use the
|

|
