Question

我有一个MySQL全文搜索引擎，我希望允许用户通过为结果添加一系列年份来过滤结果。我有一个名为year的专栏，其年份介于1999年至2011年之间。如何更改我的mysql_query以反映这一点？变量$fyear是用户想要开始的年份（低端），$tyear是结束年份（高端）。

<?php
mysql_connect("localhost", "root", "root");
mysql_select_db("database");

$var = @$_GET['q'];
$fyear = @$_GET['from_year'];
$tyear = @$_GET['to_year'];

if (isset($var)) {
$sql = mysql_query("SELECT *, MATCH(subj_name, course_name) AGAINST ('$var') 
AS score from table1 WHERE MATCH (subj_name, course_name) AGAINST('$var') 
ORDER BY score desc");
}

注意：列year是一个整数字段

Answer 1

查看运营商between。

$sql = mysql_query("SELECT *, MATCH(subj_name, course_name) AGAINST ('$var') AS 
score from table1 WHERE year BETWEEN '$fyear' AND '$tyear' MATCH (subj_name, course_name) AGAINST('$var') ORDER
BY score desc");

Answer 2

我不熟悉全文搜索，但您不能像这样添加查询条件吗？

$sql = mysql_query("SELECT *, MATCH(subj_name, course_name) AGAINST ('$var') AS 
score from table1 WHERE year BETWEEN $fyear AND $tyear AND MATCH (subj_name, course_name)   AGAINST('$var') ORDER BY score desc");

如何缩小MySQL全文搜索结果？
