Question

有关此主题的stackoverflow中有十多个问题，我阅读了大部分问题，但仍然无法搜索我的数据库...... !!! 这是我的表结构：

$sql = "CREATE TABLE content.htmlLink(
LessonID INT NOT NULL,
LessonTitle VARCHAR(512) NOT NULL COLLATE utf8_general_ci,
LessonContent TEXT NOT NULL COLLATE utf8_general_ci,
storeDate VARCHAR(32) NOT NULL COLLATE utf8_general_ci,
fileName VARCHAR(128) NOT NULL COLLATE utf8_general_ci,

FOREIGN KEY(LessonID) REFERENCES `content`.`html`(id)

);";

和父表：

$sql = "CREATE TABLE content.html(
id INT(11) NOT NULL AUTO_INCREMENT,
title VARCHAR(512) NOT NULL COLLATE utf8_general_ci,
content TEXT NOT NULL COLLATE utf8_general_ci,
storeDate VARCHAR(32) NOT NULL COLLATE utf8_general_ci,
tag1 VARCHAR(32) NOT NULL COLLATE utf8_general_ci,
tag2 VARCHAR(32) COLLATE utf8_general_ci,
tag3 VARCHAR(32) COLLATE utf8_general_ci,
tag4 VARCHAR(32) COLLATE utf8_general_ci,
tag5 VARCHAR(32) COLLATE utf8_general_ci,
PRIMARY KEY(id)
);";

向表格插入信息没有问题但是，现在我正在尝试为用户创建一个搜索引擎。我想搜索LessonContent中是否存在用户模式，所以我写了这一行：

$sql = "SELECT * FROM content.htmllink 
        WHERE MATCH(LessonTitle,LessonContent) AGAINST('$pattern')";
$query = $conn->query($sql);

//I tried to use bind param
$sql = "SELECT * FROM content.htmllink 
        WHERE MATCH(LessonTitle,LessonContent) AGAINST('?')";
$prepare = $conn->prepare($sql);
$prepare->execute( array( $pattern ) );
$fetch = $prepare->fetchAll();

//or with IN BOOLEAN MODE arg
$sql = "SELECT * FROM content.htmllink WHERE MATCH(LessonTitle,LessonContent) AGAINST('html', IN BOOLEAN MODE)";

甚至我用特定的模式检查了查询：

$sql = "SELECT * FROM content.htmllink 
        WHERE MATCH(LessonTitle,LessonContent) AGAINST('html')";

但仍然$ query是错误的。你能告诉我我的错误在哪里吗？提前致谢。我搜索了这个链接：

InnoDb（Mysql版本5.6）确实支持FULL TEXT SEARCHES。正如您所提到的那样，您的版本如下所示它不支持

使用MATCH（）搜索mysql数据库不起作用
