Add "ngram" support to MariaDB

    XMLWordPrintable

Details

    Description

      This is something added in MySQL 5.7, so perhaps it should be included in MariaDB.

      "ngram and MeCab full-text parser plugins. As of MySQL 5.7.6, MySQL provides a built-in full-text ngram parser plugin that supports Chinese, Japanese, and Korean (CJK).

      For more information, see Section 13.9.8, “ngram Full-Text Parser”
      http://dev.mysql.com/doc/refman/5.7/en/mysql-nutshell.html

      And the link referenced above is:
      http://dev.mysql.com/doc/refman/5.7/en/fulltext-search-ngram.html

      The MeCab task previously described here is now listed separated at MDEV-22987
