<font face='Verdana'>I would like to put a search engine in my website (for my own pages) and find the word "win" for instance in all the fields of my database to display them. My problem is that when I search for "win", my result page displays "win, winner", winnie.." . How can I prevent this ? U use UltraDev 4 . Here is the code on my search page :

&lt;%@LANGUAGE="VBSCRIPT"%&gt;
&lt;!--#include file="Connections/connecte_astuces.asp" --&gt;
&lt;%
Dim rs_recherche__MMColParam
rs_recherche__MMColParam = "%"
if (Request.Form("trouve" &lt;&gt; "" then rs_recherche__MMColParam = Request.Form("trouve"
%&gt;
&lt;%
set rs_recherche = Server.CreateObject("ADODB.Recordset"
rs_recherche.ActiveConnection = MM_connecte_astuces_STRING
rs_recherche.Source = "SELECT * FROM contenu WHERE explications LIKE '%" + Replace(rs_recherche__MMColParam, "'", "''" + "%'"
rs_recherche.CursorType = 0
rs_recherche.CursorLocation = 2
rs_recherche.LockType = 3
rs_recherche.Open()
rs_recherche_numRows = 0
%&gt;

and on my result page :

&lt;%@LANGUAGE="VBSCRIPT"%&gt;
&lt;!--#include file="Connections/connecte_astuces.asp" --&gt;
&lt;%

rs_recherche__MMColParam = "%"

Change this line:

rs_html.Source = "SELECT * FROM contenu WHERE explications LIKE '%" + Replace(rs_html__MMColParam, "'", "''" + "%'"

to

rs_html.Source = "SELECT * FROM contenu WHERE explications LIKE '" + Replace(rs_html__MMColParam, "'", "''" + "'"
