{DESC | DESCRIBE} index [ LIKE pattern ]

DESCRIBE statement lists index columns and their associated types. Columns are document ID, full-text fields, and attributes. The order matches that in which fields and attributes are expected by INSERT and REPLACE statements. Column types are field, integer, timestamp, ordinal, bool, float, bigint, string, and mva. ID column will be typed either integer or bigint based on whether the binaries were built with 32-bit or 64-bit document ID support. Example:

mysql> DESC rt;
| Field   | Type    |
| id      | integer |
| title   | field   |
| content | field   |
| gid     | integer |
