Teach you how to create a keyword matching project (search engine) ---- the first day, teach you to do ----

Day 1

The requirements are as follows:

1. Collect keywords and construct a keyword dictionary.

When I received this task, I thought it was not easy? Create a keyword entry interface and save it to the database. The first step was completed, and I laughed for a day. I didn't expect it to be so simple.

 

Database Configuration File: config. php

$database_host = 192.168.1.1$database_user = xiaoshuaishuai$database_password = xiaoshuaishuai$database_charset = "utf-8"

Background logic processing: keywords. php

 

<?phpinclude "config.php"$keywords = $_REQUEST["keywords"];$con = mysql_connect($database_host,$database_user,$database_password);mysql_query("SET NAMES '$database_charset'",$conn);mysql_select_db("dict",$conn);foreach($keywords as $keyword){      //save $keyword to database            $sql = "insert into keywords(word) values ('$keyword')";      mysql_query($sql,$conn);         }mysql_close($conn);

 

In Baidu search engines, search words match promotion keywords, for example?

Currently, Baidu has three matching methods: precision, phrase, and broad. Generally, the golden match method is: wide match + search term report + negative keyword. In terms of traffic, it is widely used> phrase> accurate. You can set it based on your actual situation!

How can I enter three keywords for exact match when I use a search engine?

If exact match is required, ABC must be enclosed by quotation marks.
