问题描述

我从来没有真正听到过关于这个问题的直接答案，我只需要全文搜索几个包含多个单词名字姓氏"的列

I've never really heard a straight answer on this one, I just need to FULLTEXT search a couple columns with multiple words "Firstname Lastname"

$sql = mysql_query("SELECT * FROM 
                    patient_db 
                    WHERE MATCH ( Name, id_number )
                    AGAINST ('% $term %' IN BOOLEAN MODE);");

但是如果我在这里输入一个以上的词，它就无法运行查询.

But it fails to run the query if I enter more than one word here.

推荐答案

$sql = mysql_query("SELECT * FROM 
         patient_db WHERE 
         MATCH ( Name, id_number ) 
         AGAINST ('+first_word +second_word +third_word' IN BOOLEAN MODE);");

如果你想进行精确搜索:

and if you want to do exact search:

$sql = mysql_query("SELECT * 
                  FROM patient_db 
                  WHERE MATCH ( Name, id_number ) 
                  AGAINST ('"exact phrase"' IN BOOLEAN MODE);");
