Index for TEXT field

1

Hello team

I’m trying to create the next table

CREATE TABLE IF NOT EXISTS `replacer` (
  `id_replace` int(11) NOT NULL AUTO_INCREMENT,
  `senders` text DEFAULT NULL,
  PRIMARY KEY (`id_replace`),
  KEY `senders` (`senders`(333)),
) ENGINE=ndb DEFAULT CHARSET=utf8mb4;

But I have the next error
/* SQL Error (1073): BLOB column ‘senders’ can’t be used in key specification with the used table type */

Is it possible to make Index or something more for UP speed of searching by TEXT fields?

Thanks

RonDB and MySQL doesn’t support indexes on BLOBs.
So it has to be solved on application level.
