MySQL InnoDB / MyISAM 預設的英文停用字清單

MySQL 5.7 後,InnoDB 也支援 FULLTEXT Search 了。

  • 詳見:13.9 Full-Text Search Functions
    • Full-text indexes can be used only with InnoDB or MyISAM tables, and can be created only for CHAR, VARCHAR, or TEXT columns.
    • Full-text indexes 只能用在 InnoDB / MyISAM,欄位格式支援:CHARVARCHARTEXT

InnoDB 建立自己的停用字 Table 步驟

  • 下述摘錄自此篇:13.9.4 Full-Text Stopwords
    1. mysql> use test
    2. mysql> CREATE TABLE mystopwords(value VARCHAR(30)) ENGINE = INNODB;
      -- Insert stopwords (for simplicity, a single stopword is used in this example)
    3. mysql> INSERT INTO mystopwords(value) VALUES ('Ishmael');
    4. mysql> SET GLOBAL innodbftserverstopwordtable = 'test/mystopwords';
      -- CREATE FULLTEXT INDEX idx ON table
      name(colnum_name);
