ASP uses InStr to find code for specific strings-application tips

Today, I found out that the function of the functions, can find a specific character or string.

Here's a simple example I wrote:

<% @LANGUAGE = "VBSCRIPT" codepage= "65001"%>
<% response.codepage=65001%>
<% response.charset= "UTF-8"%>
<%
Dim content_text,searchword_text

' Content is contents, Searchword is the text to search for
Sub Search (Content,searchword)
If INSTR (Content,searchword) > 0 Then
Response.Write ("Found")
Else
Response.Write ("Not Found")
End If
End Sub

Content_text = "Search bar collection of code and tutorials for Ahanan peacetime learning collection, the site's goal is to facilitate their own at the same time convenient for everyone, this site system to use Ahanan own system, the system has been written for six months, the main time on the program optimization, the program has been updated, Welcome to join Q Group to discuss study together. "
Searchword_text = "Search Bar"

Call Search (Content_text,searchword_text)
%>
