我们在自然语言模式下使用MySQL的全文搜索，但是搜索不匹配像'C++'这样的术语。 我们如何优化mysql，使其在全文搜索中正确匹配，并且不删除特殊字符？ 当然，像逗号这样的字符仍然应该被删除。
如果我理解了您的问题，您可以声明使代码易于阅读的定义，例如:
#define INSERT_INTO "INSERT INTO "
#define DELETE "DELETE "
#define VALUES "VALUES ( "
#define AND " AND "
#define JOIN "JOIN "
#define EQUAL "= "
#define LIKE " LIKE "
#define ORDER_BY "ORDER BY "
#define LIMIT "LIMIT "
#define SELECT "SELECT "
#define ALL "* "
#define FROM "FROM "
#define END_STATEMENT ";"
#define WHERE "WHERE "
#define SELECT_TRUE_FROM "SELECT 1 FROM "
